[android-developers] Missing extract UI on text input when IME shown manually without EditText widget

['Matt Perry' via Android Developers]

I have a bug where the extract UI - where the text a user types is 
displayed while in full-screen IME mode - isn't actually showing any user 
input. You can see a screenshot on our bug tracker 
here: https://github.com/flutter/flutter/issues/4899 . Any text you type 
while in landscape (full-screen) mode does not appear.

My question is: what component is in charge of showing this text? Is it the 
EditText widget? If I don't have an associated EditText, how can I display 
an extract UI?

Ours is not a typical use case, so I'll try to provide as many relevant 
details as I can:
- I work on Flutter, where our Android "app" is a full-screen Android view 
that we draw into manually. We implement our own widgets in Dart.
- Our text widgets are custom made in Dart. When a user interacts with one, 
we query the InputMethodManager and call showSoftInput 
,
 
passing in our top-level view as the view.
- We have our own InputConnection impl 
,
 
which is a thin wrapper around BaseInputConnection. It is initialized in 
response to the onCreateInputConnection call.

I can set the IME hint text, and it shows up where the extract UI should 
be. The user's input does not.

Any help is appreciated!

Thanks,
Matt

[android-developers] why zygote process name change to main in Lollipop, Is it a bug?

[perry shan]

hi,

I notice that the zygote process name change to main Lollipop , but in
KitKat and before, the zygote process name is zygote.

in Lollipop:

$ adb shell ps | grep -i zygote

root  376   1 1492064 67316   S zygote



$ adb shell cat /proc/376/stat

376 (main) R 1 376 0 0 -1 4194560 170602 262860 825 248 283 137 226 174 20

0 0 17 3 0 0 0 0 0 0 0 0



$ adb shell cat /proc/376/comm

main


in KitKat:

$ adb shell ps | grep -i zygote

$ adb shell cat /proc/329/comm

zygote


In app_main.cpp when start zygote, it will set nicename, and set the
process name with niceName.


frameworks/base/cmds/app_process/app_main.cpp


int main(int argc, char* const argv[])

...

if (strcmp(arg, --zygote) == 0) {

zygote = true;

niceName = ZYGOTE_NICE_NAME;

...

if (!niceName.isEmpty()) {

runtime.setArgv0(niceName.string());

set_process_name(niceName.string());

}


but in new AndroidRuntime ART, the will change the name zygote to main

if (zygote) {

runtime.start(com.android.internal.os.ZygoteInit, args);

 The string array elements replace the question mark placeholders.
 SQLite handles quotation rules for strings for you, so you do not have
 to worry about embedded quotes or apostrophes.

[android-developers] Re: Working with VideoView without calling MediaPlayer.release()

[Christopher Perry]

I'm also having this issue, I'd like to see a resolution to this
because my application relies heavily on video and the Android
MediaPlayer doesn't work very well. I'm not sure what else to do at
this point.

 Hi !

 Today, this issuehttp://code.google.com/p/android/issues/detail?id=959has
 become really problematic for me.

 MediaPlayer.release() makes my applications hang for a few seconds very
 often. As it makes the user experience really unacceptable I have copied the
 source code from VideoView and removed calls to MediaPlayer.release(),
 nevermind the lost resources. My application is now mush smoother. My
 application adds and removes the videoview when needed. But sometimes, after
 readding the custom VideoView, it will be black or green, complaining about
 Surface Overlay being busy. Messages differs for every hardware.

 So here is my question : Is it possible to live without calling
 MediaPlayer.release() ? (this method can block my UI so I can't use it)
 If not, which workarounds are available ? I have tried to call this method
 in a different thread but it will release the resources to late for the next
 SurfaceView;

 Any ideas ?

I had a similar problem, the problem was caused by a google cancelled order,
due to credit card failure.  The solution was to change the sort order by

then you can go in and archive or delete those entries, it all worked fine
after that.

[android-developers] Global Plugin.

[Ken Perry]

 

 

I am trying to find out if there is a way to add a global WebKit plugin so
that any programming using the WebView will have my plugin in attached.  The
plugin will need access to the NP Navigation and dom.

 

I looked at the example under development Samples for browser plugin but
that only works in the browser and only if you include the code in the web
page.  I need it to work on any  web page.If you have any ideas I can
take you off list and give you a more clear idea of what I am wanting to
accomplish.

If by any programming using the WebView refers to the device as a
whole, you can only do this by modifying the firmware, AFAIK.

[android-developers] Javascript, WebView, and arrow keys.

[Ken Perry]

The following question has to do with Froyo 2.2 sdk 8 running on an
emulator.

 

 I am injecting Javascript  into a web page and in the WebView activity I
get 19, 20, 21, and 22 for key codes for arrow keys.  At the Javascript
level all four arrow key values in a keydown handler come in as zero.  The
following is the java script code I am using to set the handler and to get
the keyValue.

 

window.addEventListener('keydown', keyDownHandler, true); 

 

function keyDownHandler(evt){

var keyCode=evt.keyCode;

myLog(keyCode);

}

 

 

I will note that keys like enter come in correct for example I get 13 for
enter.  I also will note that if I press shift and then an arrow key I get
16 for all 4 arrow keys instead of 0.  myLog function takes a String but the
following works 

 

If (keyCode==0){

myLog(arrow key);

}

 

So the value is coming in as zero is there some way I can fix this.  If
someone has time I have a pretty simple example of this problem I could
probably zip up as an eclipse project.

 

Thanks,

 

Ken

RE: [android-developers] Re: How to debug web page on device?

[Ken Perry]

I think you're doing it the same way I am.  I use addJavascriptInterface to
add logging class to any JavaScript I write.  Then I can use the Android
Java log class to write to the log cat.  I tag the logs with the keyword
javascript so I get a nice neat list of whatever I want to see.

Subject: [android-developers] Re: How to debug web page on device?

Debugging webview can be tricky. A lot of the errors print in the
console. Mostly the problems aren't going to be actual JavaScript
errors if it renders fine in other devices but will be due to some
oddity in the way a particular manufacturer implemented webkit. I've
seen lots of differences in the devices. HTC is particularly odd.
Motorola is particularly good. I haven't dealt with the Samsung
variants yet but I hope they are closer to Motorola than HTC.

One way you can debug webview is to put a function in your app that
logs messages from the webview with JavaScript calls. Then sprinkle
those calls liberally throughout the JavaScript and just monitor what
happens. Look for differences in the way the devices render things.

I use this method and have found it cumbersome but effective. I use a
lot of webview stuff so if someone else knows a better way, I'm all
ears.

[android-developers] Having problems referencing a library project from an application

[Christopher Perry]

I've been trying to do this now for 2 whole days, and am about to give
up. I followed the instructions here:

http://developer.android.com/guide/developing/eclipse-adt.html

but it is not working. I can see the library project is added to my
application but I cannot reference anything in it. Also the R.java
file from the lib was NOT added to my application, so the lib project
contains tons of errors, everywhere it tries to reference it's own
R.java file (most likely the cause of the former).

Also, in the console there are messages stating that the there is No
resource identifier found for attribute 'X' in package 'Lib Package'.
The library builds just fine, and I don't get those messages in the
console until I hook the library to my application.

You would think that creating and referencing a library would be a
simple thing to do, as it is in most other projects, but this is
turning into a real nightmare. Thanks Google!

[android-developers] Re: Android Library Project

[Christopher Perry]

I'm having this exact problem right now. Did you figure it out?

 Hello Mark,

 I faced the same problem with attrs.xml in Library Project. Have you
 finally found the solution?

  I'm sure that thelibrary.apk file error was because I had added 
  thelibraryprojectto my appprojectbuild path.

  The other problem, where appprojectclasses could not 
  seelibraryprojectclasses was due to something else.

  For some strange reason, even when the androidlibrarycompiles by
  itself (I mean, does not show any errors in eclipse), it can give
  compiler errors when used as alibraryin anotherproject. In that
  situation, it does not show up like LibProject in your png file.

  In my situation, this was caused by a problem with a custom widgets I
  had defined in mylibrary. The attrs.xml file was being ignored for
  some reason. Everything worked fine (i.e. the LibProject showed up as
  in your png file) when I removed those custom widget (I'm not talking
  about homescreen widgets)attributesfrom the relevant layout xml in
  thelibraryproject.

  Sorry all this is a bit vague. I'll try and come up with a clearer
  scenario but I'm right in the middle of something now.

[android-developers] Problem after implementing SQLiteOpenHelper

[Christopher Perry]

I have a ListActivity that uses a CursorAdapter to fill the rows in
the view. I wrote a database helper class that gives me back results
for common queries I make for my app, and it uses an SQLiteOpenHelper
implementation I wrote to open the database. I use the open helper to
open the database and get a cursor to pass to my CursorAdapter. Here's
a code snippet:

public static Cursor getCursor(DbOpenHelper openHelper) {
SQLiteDatabase db = openHelper.getWritableDatabase();
db.beginTransaction();
Cursor c = null;
try {
String sql = select * from  + TABLE_NAME;
c = db.rawQuery(sql, null);
db.setTransactionSuccessful();
} catch (SQLException e) {
Log.e(Exception on query, e.toString());
} finally {
db.endTransaction();
}

return c;
}


The problem I'm having, that I didn't have before I implemented the
open helper (before I just opened the database directly without a
helper), is when I click on an item, which takes me to another
activity, and then go back to this activity. When it initializes
everything is fine, and my list is populated fine, but when I go back
from the activity that follows, the list is empty and in the LogCat I
see Invalid statement in fillWindow().

It appears from a few post I've seen that the reason is, when I
requery the cursor, the database is closed. But I'm not closing it!
I'm scratching my head on this one.

[android-developers] Changing entry activity causes app only to open from downloads page

[Christopher Perry]

I recently added an activity to one of my apps, and made it the
starting activity for the application and published an update. The
update worked perfectly with no problems on my N1, but I'm getting
emails from users telling me that the only way they can open my app is
from their Downloads page in the Android Market app. I have no clue
what could be causing this behavior, PLEASE HELP!

 We're looking on making an app that would interact with SMS's so it

 the long press menu of a sms to call it to play the said message.

[android-developers] Text to speech

[Ken Perry]

I have looked through the archives and have seen that some people were
trying to get Free TTS to work with Android.  I personally don't like free
tts but with that said did anyone ever get it to work.  If not has there
been any more news  about TTS being added to the Android SDK?

I did search the group before posting this but I never saw a conclusion to
the discussion.

Ken
