[android-developers] Own app dialer

[Руслан Подурец]

Wanna to implement own dialer activity, but don't know how to show chooser, 
where user can choose my app as dialer. Found billions link how to catch 
calls or open chooser like this: link 


But this not fits to me. Need only to show chooser dialer dialog without 
make call after choose. Just only choose default dialer.


I added uses permission to manifest:



Also added a lot intent filters to activity:











































I tried different ways, but cannot find right solution how to show chooser 
dialog, where user can choose default app for dial.
F.e:

Intent selector = new Intent(Intent.ACTION_DIAL);
selector.setData(Uri.parse("tel:598578"));
startActivity(selector);  - This not right, and not works - want only to 
show chooser, where user can choose app.  

Intent selector = new Intent(Intent.ACTION_DIAL);
startActivity(selector); - not works.

try {
Intent dial = new Intent(Intent.ACTION_DIAL);
dial.addCategory(Intent.CATEGORY_DEFAULT);
startActivity(Intent.createChooser(dial, "Choose dialer..."));
} catch (Exception e) {
Toast.makeText(StartTest.this, "Activity not found", 
Toast.LENGTH_LONG).show();
} - Not works


Will be glad any link or proposals.

[android-developers] InAppPurchase: Consumption Request to Google Play

[Andre]

Hello,

i want to add some consumable in app items for my game. But the only choice 
is:

- Managed Item
- Abo

The documentation says:

Before provisioning the consumable in-app product in your application, you 
> must send a consumption request to Google Play and receive a successful 
> response indicating that the consumption was recorded.

 
But where i can do that?

Thank you and best regards

Andre

[android-developers] Re: Build app using video camera that stores separate preferences and doesn't prompt to save videos

[gjs]

Hi,

See http://developer.android.com/guide/topics/media/camera.html#capture-video

For (1) As per the link provided, ordinarily the video is saved to (the 
nominated) file automatically, there is no prompt to save or discard the 
(video) file, that would require extra effort if you did wish to discard 
the file, via a Dialog screen of some sort.

For (2) You can save (and read) your custom "camera" properties as Key 
Value pairs from persistent memory using SharedPreferences, 
see 
http://developer.android.com/reference/android/content/SharedPreferences.html 

If you wish to edit your custom "camera" property values you probably need 
to develop an Activity screen or perhaps just a Dialog if you only have a 
few things to configure for the camera.

Regards

[android-developers] jobscheduler how to

[Zhihong GUO]

Hello,

I create a jobscheduler in onReceive method of boot complete receiver. The
job is not scheduled to run after two minutes. The device is in idle and
wi-fi connected.

Can anyone give help?

Thanks,

context.getSystemService(Context.JOB_SCHEDULER_SERVICE);
tm.cancel(JOB_ID);

JobInfo.Builder builder = new JobInfo.Builder(JOB_ID, new
ComponentName(context, TestService.class));
builder.setPeriodic(TWO_MINUTES);
builder.setPersisted(true);
builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED);
builder.setRequiresDeviceIdle(true);

tm.schedule(builder.build());
}

then in the TestService


@Override
public boolean onStartJob(final JobParameters params) {

Log.i(LOG_TAG, "job started");

new Thread(new Runnable() {
@Override
public void run() {
//do something here, then call jobFinished

[android-developers] FusedLocationApi does not update location with out interent

[Shashidhar]

Hi,
 I have implemented the frequent location updates in my app following the
training @
http://developer.android.com/training/location/receive-location-updates.html .
Every thing works fine when the phone is connected to internet. But the
location does not get updated when there is no internet connection?
Is this expected behavior or do we have a workaround to get the location
updates with out internet? We even tried with setting the priority as
PRIORITY_HIGH_ACCURACY

while
initializing the location request and that did not help with out internet.

Appreciate your Help!

Thanks,
Shashidhar

[android-developers] Need help with Tracked channels (UTM) in google play console

[mohan krishna]

Need help with Tracked channels (UTM) in google play console (user 
acquisition) please.
I want to track which source is giving me more installs in developer 
console user acquisition section.
I used this link 
https://developers.google.com/analytics/devguides/collection/android/v4/campaigns#google-play-url-builder
 
to create urls for different sources and placed them in different sources 
from where i get users. But i don't see any measurement in my user 
acquisition-> performance page in google developer console, even after more 
than one week, i can see other numbers like "Play Store (organic)" for same 
date but "Tracked channels (UTM)" is still zero even after one week.
Thank you in advance for the help.

[android-developers] Different vertical alignment between Android >=5.0 and < 5.0

[lorenzo sfarra]

Hello everyone,

I suspect that this can be a well known problem, if it's true, but I cannot 
find anything in this direction...I cannot only find a lot of topics on how 
to generally vertically align elements.

So, I have this layout part:


 
 




Now, when I run this code on an Android version >= 5.0, both the ImageView 
and the TextView are perfectly vertically centered (and the TextView is 
centered with respect to the image, too).
When I run this code on an Android version < 5.0, the TextView is almost at 
the same level of the top of the ImageView.

Can you please provide me any info about this problem, please?

Thanks in advance,
  Lorenzo

[android-developers] Run CheckBox toggle animations in a RecyclerView using DefaultItemAnimator

[Csaba Kozák]

I have a RecyclerView, which has CheckBoxes as item views.
My bind method is pretty simple:

checkBox.setChecked(modelItem.isChecked());



I am using the default DetaultItemAnimator for the RecyclerView.
What i want to achieve is if the list item is currently in the viewport, 
run the nice toggle animation on the checkbox when the underlying model is 
changed.
(But the animation should not be shown when the item is just rebound, for 
example when the item is scrolled into viewport).

Currently there is no toggle animation at all, because of this 

 
line i think.

Is there a way to achieve my goal?
Thanks.

Thanks.  I was able to find a small example app to use as a base for this: 
http://examples.javacodegeeks.com/android/core/android-video-capture-example/ 
.  It had some bugs wrt proper ordering of sources, encoders, and formats 
(pretty gnarly to get it all right, and I'm fairly certain it isn't 
bulletproof yet), but it's basically working as advertised.  Now I have to 
make several adjustments to get it closer to what I need.

[android-developers] Layout structure to display button over camera preview (like in stock camera app)

[David Karr]

I'm working with a sample video capture app 
(http://examples.javacodegeeks.com/android/core/android-video-capture-example/).
  
I've made some changes to it, but the basic structure is the same.  The 
layout used displays the preview in a pane on the left side of the screen, 
with a layout containing buttons to the right.  I really need the preview 
to take up the entire screen, and have the button (I'm only going to have 
the "Capture" button, not the "switch camera" button) display at the bottom 
center, just like the stock camera app.

This is really just a layout question.  Can someone show the basic 
structure that would display a single button at the center of the bottom, 
displayed on top of the camera preview?

[android-developers] Android navigation drawer custom design

[naman khator]

down votefavorite 


I want to create a navigation drawer which would look something like:

https://dribbble.com/shots/1535815-iShop-Menu-Slide

Is it possible? If yes what should I do. I have no idea where to start 
from. I am guessing I will need to customize the activity layout on drawer 
open/close like making its height and width small by something like this:

http://stackoverflow.com/a/21038169

But if anyone could help me get a kickstart, a code snippet or any relative 
link it would be great.

Thanks

[android-developers] Re: How do it Display Bitmaps frames per seconds in an ImageView efficiently ?

[gjs]

Hi,

Why not just -

@Override
public void onFrame(final Bitmap mBitmap) {
 try {
if (mBitmap != null && headerImageView != null) {
headerImageView.setImageBitmap(mBitmap);
}
} catch (Exception e) {
e.printStackTrace();
}
  
}


Regards

[android-developers] Android MVVM framework write in kotlin

[Benny Wang]

I'm work on a project KBinding(https://github.com/BennyWang/KBinding.git) 
which work on the binding between View and ViewModel.
Views are created by Anko DSL like 

class MainActivityUI : ViewBinderComponent {
override fun builder(): AnkoContext<*>.() -> Unit = {
verticalLayout {
verticalLayout {
backgroundColor = Color.WHITE
leftPadding = dip(14)
editText {
hint = "请输入手机号或者电子邮箱地址"
bind { text(path="name", mode = BindingMode.TwoWay) }
}.lparams(width = matchParent)
view { backgroundResource = R.color.color_f2 }.lparams(width = 
matchParent, height = 1)
editText {
hint = "请输入密码"
bind{ text(path="password", mode = BindingMode.TwoWay) }
}.lparams(width = matchParent)
}.lparams(width = matchParent)
textView {
text = "登录"
textSizeDimen = R.dimen.font_38
textColor = Color.WHITE
verticalPadding = dip(10.4f)
isClickable = true
bind { click("login") }
bind { enabled(paths=listOf("name", "password"), converter = 
ArrayToBooleanConverter()) }
}.lparams(width = matchParent) { margin = dip(14) }.let { 
it.gravity = Gravity.CENTER }
}
}
}


ViewModel like this

class LoginViewModel(val delegate: LoginViewModel.LoginDelegate) : 
ViewModel() {

var level: Int by Delegates.bindProperty("level", 3)
var name: String by Delegates.bindProperty("name", "...@x.com")
var password: String by Delegates.bindProperty("password", "x")

val login: Command by Delegates.bindCommand("login", Command { it ->
if(name.equals("wangbin")) delegate.onLoginSuccess("wangbin")
else delegate.onLoginFailed(RuntimeException("incorrect name or 
password"))
})

interface LoginDelegate {
fun onLoginSuccess(s: String)
fun onLoginFailed(e: Throwable)
}
}



once binding, the change of viewmodel property will change the display of 
view.

[android-developers] Re: FusedLocationApi does not update location with out interent

[gjs]

Hi,

For frequent / accurate location updates try 
http://developer.android.com/reference/android/location/LocationManager.html 
and the onboard GPS receiver, unless of course you have a Pixel C tablet 
which has no onboard GPS receiver ;-)
