[android-developers] How to send an specific key event to FG app using adb?
Hello, I want to keep launching my app and stress test two scenarios: launch it and press BACK key launch it and press MENU key I can launch from adb using am command. But how can I send a BACK or MENU key using adb. I want to do thousands of rounds of testing so I don't want to do it manually.

[android-developers] Re: How to dump all thread stacks?
I ended up writing an app that sleeps forevern in an event handling
function. Whenever I need to dump stacks, I just run this app and then
adb pull /data/and/traces.txt

[android-developers] Re: Froyo -- How to detect that my application has been killed?
Hi Dianne,
I understand that we need to handle app killed by LMK. If we can
handle LMK, we can also handle the new Froyo kill-by-task-manager
behavior.
Do you have any suggestion about this:
For example, let's say our app creates a 10MB cache file. When the app
exits, we want to delete this cache file. How to do this in the case
of killed-by-LMK?
Is there any suggestion better than just don't use a large cache
file?
BTW, there are a lot of code in Froyo system services that rely on
Intent.ACTION_PACKAGE_RESTARTED (such as StatusBarService). I think
these probably need to be fixed.
Thanks!

As I said, the ONLY thing app killers can do now is the same thing that the
OOM killer does when it needs memory, and this NEVER involved a broadcast.
You have lost nothing here from previous versions of the platform.

[android-developers] Re: Froyo -- How to detect that my application has been killed?
As far as a cache -- you shouldn't count on your process being evicted to clear a cache. This has problems the other way -- there is no guarantee your app will be killed *ever* while in the background, since it may never clear its cache. You should use other policies for this. For example, after a certain amount of time (via the alarm manager maybe), etc. I could wait a little time after going in BG, and then clear cache. But what if the app gets killed before my timer expires? I can't clear cache immediately on going to BG, or else the app performance will suck. Is there a solution to this dilemma? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Froyo -- How to detect that my application has been killed?
Dianne, here's the reproduction step on Froyo: [1] Run on Froyo - start ApiDemos, start the RemoveService sample. You will now see two processes com.example.android.apis com.example.android.apis:remote [2] You will notice that Sample Remote Service appears on status bar. [3] write an app with KILL_BACKGROUND_PROCESSES permission. Call ActivityManager.killBackgroundProcesses(com.example.android.apis); [4] Both processes created at step [1] are killed. [5] RemoveService is never restarted, even though you see something like W/ActivityManager( 2426): Scheduling restart of crashed service com.example.android.apis/.app.RemoteService in 2ms [6] Sample Remote Service message still stays on status bar. This is because StatusBarService expects a ACTION_PACKAGE_RESTARTED broadcast, but this braodcast is never delivered. What's the best way to handle this -- we need to clean up some resources if the app process is killed. Thanks!

so free to be killed, and once it gets killed the binding goes away and the

But this exact behavior is expected to happen when the device is low on
memory, so it is something apps need to deal with correctly anyway.

Um yeah the check for process priority does let it kill service processes

That said, the service *does* restart like it always did, and I have
confirmed it does. That code path hasn't changed at all. So basically the
behavior is still like it was pre-2.2, except there are still some processes
that can unintentionally be killed.

[android-developers] Re: Using a permission that doesn't exist
I found my answer: If an app uses a permission that's not defined on your phone, it is still displayed in Android Market. When you try to install it, the undefined permission is NOT displayed to the user, and is NOT granted. So later, if you later install the service that defines (and requires) the permission, the first app will NOT be able to access the service. The only apparent way to fix this is to reinstall the application, which is hard to do with Android Market unless (a) a new version of the app is posted; or (b) the user uninstalls and re-installs the app. (b) will suck because you lose preferences and data saved by the app. On Feb 10, 11:20 am, tomei.ninge...@gmail.com tomei.ninge...@gmail.com wrote: I saw onhttp://developer.android.com/guide/topics/security/security.html that my app can declare a permission: manifest xmlns:android=http://schemas.android.com/apk/res/android; package=com.me.app.myapp permission android:name=com.me.app.myapp.permission.DEADLY_ACTIVITY android:label=@string/permlab_deadlyActivity android:description=@string/permdesc_deadlyActivity android:permissionGroup=android.permission-group.COST_MONEY android:protectionLevel=dangerous / /manifest So if another app Foo need to invoke the deadly activity, it would declare the following in its Manifest: uses-permission android:name=com.me.app.myapp.permission.DEADLY_ACTIVITY / However, what if com.me.app.myapp is not yet installed on the device?

[android-developers] How to achieve ultra smooth OpenGL/ES animation
Hello Android OpenGL/real-time gurus, I am drawing a pretty simple scene, with one large texture the about size of the screen (two triangles). I notice that the frame-rate is irregular: in most of cases, a frame finishes in 17 ms. However, in about 1 of 10 times, the frame finishes in 33ms. My guess is probably some background services need to run. However, the Linux scheduler is biased towards my FG app, so the BG services are usually starved, until they can't take it anymore and they grab the CPU from my app I am seeing stuttering in the animation. Is this due to the irregular frame rate? Should I delay each frame so that all frames are rendered with 33ms frame time? If so, what's the best technique of achieving this? Is there an API that I can call to guarantee CPU resources for the render thread I really hope Android runs on some sort of real time kernel ...

Thanks for the suggestion. I forced GC before starting the animation and I can verify that no GC log comes in logcat, but still I am seeing stuttering in the animation.

Whenever the garbage collector is called, you can see a message in the logcat, under the tag dalvikvm, using log level debug. If it is the GC, the way to fix it is to avoid allocating memory: every time you allocate memory, the GC wakes up to check if there is something to collect; just pre- allocate all the objects you need, and that´s it. You can also call the GC manually, when the timing is good for you, using the System.gc() call.

I am already doing the animation in a time-based fashion. However, when I scroll the texture at a constant speed across the screen, I can see stuttering when the frame rate changes between 60fps and 30fps. Apparently the human eye is very good at detecting this kind of anomaly. On Feb 1, 4:35 pm, Robert Green rbgrn@gmail.com wrote: What MrChaz said.

SoftwareForMe.com wrote: I guess Google expects others to fill the void and build business around the services we all need. For example, online market listings: there are now many. How can anyone build such a business when the market data is not available (without hacking, etc)? I have used many of the online market listings. None of them allow me to contact the user. Only one allows viewing multi-language comments, but that's very clumsy to use. I am frustrated because Google has all the data. If it decides just to lift its little finger for a few engineer-days, the data can be exported to Developer Console. And Google has not done anything for more than a year.

Hi Nemat, Thanks a lot for your help! I have an app that shows up on other Android phones but don't show up on Android Market in Tattoo. I tried following the Google documentation as well as HTCs http://android-developers.blogspot.com/2009/10/support-for-additional-screen.html http://developer.htc.com/htc_tattoo_developer.html I already have uses-sdk android:minSdkVersion=3 android:targetSdkVersion=4 / supports-screens android:largeScreens=true android:normalScreens=true android:smallScreens=true android:anyDensity=true / uses-permission android:name=android.permission.INTERNET/ uses- permission uses-permission android:name=android.permission.WRITE_EXTERNAL_STORAGE/uses- permission uses-permission android:name=android.permission.ACCESS_NETWORK_STATE/uses- permission but still my users report that they can't see my app. It's very frustrating for me because I don't have a Tattoo phone. If you have time, could you tell me the names of a few apps that show up on your Tattoo phone? I will download them on my own G1 phone and examine their AndroidManifest file, to see what their success story is. I didn't want to go down this path, but I really can't afford to buy every phone out there to test compatibility. Thanks!

[android-developers] DROID so buggy (OpenGL) -- and work around
I found that on DROID OpenGL implementation acts very differently than
all other 1.5 and 1.6 phones.
Bug (1): I have a SurfaceView that has getVisibility() ==
VIEW.VISIBLE, but is completely hidden by another view. When I am in
portrait mode, and pull open the keyboard, the screen orientation does
not change. In fact, the UI is frozen and does not accept any key or
touch input. The only way to get out is to use the HOME hardware
button to go back to home screen, and then return to the app, at which
time the orientation is finally changed and UI takes input again.
The work around is this:
public void onConfigurationChanged(Configuration newConfig) {
mSurfaceView.setVisibility(View.INVISIBLE);
super.onConfigurationChanged(newConfig);
}
Bug (2): the workaround in (1) causes this problem -- when SurfaceView
that has getVisibility() == VIEW.INVISIBLE, and user presses HOME
button to pause the app, and then launches the app again, the
SurfaceView becomes black (even if I get a supposed callback that
tells me that surface is created, at which point I reloaded all of my
textures). The work around is here -- in conjunction with the above
protected void onPause() {
super.onPause();
mSurfaceView.onPause();
mSurfaceView.setVisibility(View.VISIBLE);
}
protected void onResume() {
super.onResume();
mSurfaceView.setVisibility(View.VISIBLE);
mSurfaceView.onResume();
}
So far these hacks seem to work fine on 1.5, 1.6 and DROID, but I am
really worried that as Android advances and fragments, eventually my
OpenGL app will get crushed by the rate of change and apparent lack of
testing by Google.

[android-developers] Re: screen compatibility not quite right
I have to say that Android's screen compatibility worked out really well for me. My app specifies all positions using DIPs, and it worked on the DROID without any change (or even recompilation -- the app was built using SDK 1.1). Essentially all screen coordinates were scaled by 1.5, and bitmaps were also scaled by 1.5, in BOTH directions. The only problem I still have is with WebView + JavaScript. The coordinates returned by obj.offsetTop, etc, in JavaScript are shrunk by 1.5x when running on DROID, even if I specified the following in AndroidManifest.xml: supports-screens android:largeScreens=true android:normalScreens=true android:smallScreens=false android:anyDensity=true / That wasn't too hard to work around, but I wonder if there's a disable compability mode switch in WebView On Nov 22, 12:16 am, Dianne Hackborn hack...@android.com wrote: On Sat, Nov 21, 2009 at 4:26 PM, Mark Murphy mmur...@commonsware.comwrote: DROID has been optimized to display wide-screen multimedia (movie) content at its native aspect ratio of 16/9. This is different from the HVGA aspect ratio of 3/2, which is the traditional computer screen format. What this means is that when content is scaled up to full screen, the horizontal (X*1.5) and vertical (Y*1.77) scaling factors are different. As a result, when displaying the same bitmap as a full screen background, round circles can appear as ovals, and squares are elongated to rectangles. http://developer.motorola.com/docstools/library/Support_for_Multiple_... I have no reason to believe this is DROID-specific, but rather is how Android scales things in WVGA800/WVGA854, when you do not supply your own pre-scaled resources. I think what they are trying to say is correct, but probably misleading. First, scaling is only done based on density, and does NOT change aspect ratio. If you are on a high density device, and your assets are medium density, they will be scaled by 1.5 in both width and height, period, end of story. What this Motorola doc is describing is what I would consider a special case. If you make a layout that is fill parent for both width and height, then on a WVGA of course it will be taller than on HVGA because the screen you are filling is taller. Now if you set a drawable as its background, the View class draws its background by simply stretching the drawable to fill its contents, so your bitmap will be stretched to fill whatever aspect ratio your layout has ended up being. This is just a matter of accounting for the screen being different sizes and designing your layout to adjust accordingly. You cannot control the aspect ratio, as that is dictated by the physical parameters of the screen. AFAIK, there is no Android equivalent of letterbox that would put black bars on either side of your app and give you a smaller virtual screen with 3/2 aspect ratio. We actually do a postage stamp for apps on large screens, since we found that a significant number of them broke when given so much extra space. However, the vast majority of existing apps work reasonably well when presented with a WVGA screen, so rather than cause all of the existing ones to not be able to use that space, we decided to not provide compatibility for that and live with the small handful that did have significant problems. But for someone writing an app today, this is fairly irrelevant, because if your app really can't use anything more than an HVGA screen then you really just need to design your layout to center or whatever you want your content in whatever screen you are running on. Also in my layout I am positioning some items using pixel positions. Should I convert these to dpi? If you mean dip (density-independent pixels), perhaps. It depends on what the pixels represent. There is no hard-and-fast rule. But the vast majority of time, yes, you do want to use dpis. However! The original post showed that the app was actually saying it can't deal with densities. This means the system will emulate a medium density screen on whatever density the device is, so 1 px == 1 dip. However, you really should not be saying that you don't support densities -- there are artifacts that can happen when doing this, such as font metrics not being quite right. If you are writing an app today, you really want to not put yourself in compatibility mode, and just write the app correctly. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

[android-developers] Bug in GLSurfaceView.RENDERMODE_WHEN_DIRTY (and work-around)
My OpenGL app animates only every now and then, so I decided to use
RENDERMODE_WHEN_DIRTY to save some battery life. However, I found that
when I go to Home Screen and return to my app, I often get a black
screen, and I see this in logcat:
E/SurfaceComposerClient( 6055): using an invalid surface id=1,
identity=735 should be 738
This seems to be caused by this code in GLSurfaceView (1.6 here, but
2.0 has same problem):
synchronized (this) {
if (mPaused) {
mEglHelper.finish();
needStart = true;
}
while (needToWait()) {
wait();
}
...
}
if (needStart) {
mEglHelper.start();
..
If I use RENDERMODE_WHEN_DIRTY, I will be stuck inside the wait()
call. When my app is paused/resumed, GLSurfaceView.{onPause,onResume}
will be called, by the change in mPaused will be lost. So when wait()
finally finishes, the mEglHelper.finish() and mEglHelper.start() lines
are not executed, and I end up drawing into the wrong surface.
The work around is simple but a bit ugly:
public MyView() {
super();
setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
}
public void onResume() {
super.onResume();
setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
requestRender();
}
public void onPause() {
setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
android.os.SystemClock.sleep(60);
super.onPause();
}
The trick is to temporarily get the GLSurfaceView to run in
RENDERMODE_CONTINUOUSLY. I found the sleep(60) to be necessary to
avoid race conditions that somehow left me hanging inside the wait()
but I am not sure if this is 100% scientific.
Anyway, cheers, and save a few battery bars!
P.S., I found this to be somewhat disconcerting ... as the longevity
of this bug shows not too many people are trying to use OpenGL to make
their UI faster -- and battery efficient. This probably means that
iPhone apps will continue to look-and-feel better than Android for
quite some time :-(

[android-developers] Re: hidden APIs in Android
I tried and it worked. You are right that if you use the SDK straight you won't be able to compile such code. However, if you replace the API jar file from the SDK, then you can build such apps with calls to hidden APIs. So it seems Android doesn't really try to prevent you from using hidden APIs (not that this is recommended for production apps) so as long as you could build the APK file you're good to go -- at least for the specific version of Android on the specific handset that you're targeting. For me that's good enough as I was just writing a demo.

[android-developers] hidden APIs in Android
There are a bunch of APIs that are hidden using the @hide tag so they are not exposed in the SDK. If I call these APIs anyway, does the VM actually prevent me from doing that (in dexopt stage, etc)?

[android-developers] How to force hw.lcd.density for a specific app
Hello, Is it possible to force Android to use a given LCD density value? For example, if the app is running on a WVGA phone that reports LCD density of 160DPI *and* screen size of 3.7inch, one of those two values must be wrong. Is it possible to tell Android to ignore the 160DPI value and use 240DPI instead (for my Activity only)?

Is there a way to tell Android keep using full network speed even when screen is blacked out?

[android-developers] Re: WebView.loadDataWithBaseURL bug
I found the ultimate work-around. After the page is loaded, iterate
through all links, and manually fix the ones that are problematic:
function markup_links() {
for (var i=0; i document.links.length; i++) {
var li = document.links[i];
if (li.href == ..) {
/* fix the li's style to an inactive link */
}
}
}
I just run this code at the end of the data to be loaded into WebView.

there are some strange things associated with loadDataWithBaseURL()

base URL instead of the provided data, i've never really got to the
bottom of it.
another thing you are probably running into is that
shouldOverrideUrlLoading() is not called on reloading the same page.
that's a nasty bug that's caused me some trouble. sounds like you can
work around it by faking a parameter, but that didn't work for me in
my case.

Has anyone seen this?
webView.loadDataWithBaseURL(http://www.google.com;,
a href=http://www.google.comclick/a, text/html, utf-8, nul);
webView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLloading(WebView w, String url) {
System.out.println(url);
return true;
}
});
When user clicks the link, my shouldOverrideUrlLloading() function is
not called. Instead, the WebView just goes out to fetch the real
www.google.compage.
For the time being, my work-around is to append ?foo=bar into the
baseURL.
Is there a better work around?
Thanks

[android-developers] How to create multi-language application?
I read http://developer.android.com/guide/topics/resources/resources-i18n.html. But it shows how to localize your app for the currently selected locale of the phone. However, I want to add a language option into my own app, and allow the user to switch the UI language independent of the phone's locale setting. My currently solution is to manage a string table myself, and dynamically edit the text string of every UI element. However, this is rather tedious. Is there a better way?

[android-developers] Re: save new file into asset directory from app
I know one way that works for sure. Open a server socket inside your app, then specify http://localhost:1234 inside WebView. This seems like a hack (and maybe it is :-) but it's much simpler than fighting with WebView.

But don't know why this is happening. I will make small app and will try to open an issue on this if could not get answer on this forum. Ideas from the experts are very much welcome.

I am very much *not* a CSS expert. With that in mind: -- have you tried fully-qualifying the URL you use with @import? -- is there a reason you use @import versus a stylesheet link element? Also, since I do not see a bug report for this out onhttp://b.android.com, if you can create a small project that reproduces the error, you might want to open an issue on it, so that it is more likely to get investigated. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Android Development Wiki:http://wiki.andmob.org -- jason.vp.engineering.particle --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
