apkbuilder was deleted, how to replace it?

Felipe Monteiro de Carvalho — 2013-05-18T07:24:56

Hello,

I wish to build Android applications in Windows while having to install the 
smallest amount of stuff possible. In particular without installing ant.

So I developed my own batch script which builds the APK. It uses the tools 
that come in the SDK and it has worked great for something like the last 2 
years.

Today, sudenly I was setting up a new computer and found out that my script 
no longer work! Because Google removed the vital apkbuilder script =(

This line in my script stopped working:

call apkbuilder %APK_PROJECT_PATH%\bin\%APP_NAME%-unsigned.apk -v -u -z 
%APK_PROJECT_PATH%\bin\%APP_NAME%.ap_ -f %APK_PROJECT_PATH%\bin\classes.dex 

Does anyone know what is the new command that I should use that is the new 
way to do things according to Google?

I tryed to Google but only found that the new way is some Java class ... 
but I am running a batch script here, so I have no idea how I would call a 
java class from my script.

Any ideas how to make my script start working again?

Not using ant is a must-have requirement for my script, so please no 
solutions which involve using ant.

thanks in advance,

Unable to send BroadCast

Abhilash baddam — 2013-05-18T03:18:38

Hi,

I am having two apps in which one app(AppA) consists only BroadCastReceiver
and another app(AppB) is having an Activity from there I am sending a
broadcast to the AppA.
But I am not getting any event in AppA in which I have implemented the
onReceive function.

*AppA and it's manifest file:*
public class AppA extends BroadcastReceiver{

< at >Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equalsIgnoreCase("com.MyAction")){
String s  = intent.getStringExtra("MyValue");
}
}
}

manifestFile:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.justreceiver"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="< at >drawable/ic_launcher"
        android:label="< at >string/app_name"
        android:theme="< at >style/AppTheme" >
        <receiver
            *android:name="com.example.AppA"*
            android:label="< at >string/app_name" >
            <intent-filter>
               * <action android:name="com.MyAction" />*
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </receiver>
    </application>


*Application B from where I am sending the broadcast:*
*
*
public class AppB extends Activity {

    < at >Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button send = (Button)findViewById(R.id.send);
        send.setOnClickListener(new OnClickListener() {
 < at >Override
public void onClick(View v) {

Intent i = new Intent();
i.setAction("com.MyAction");
i.putExtra("MyValue", "Yahooooooo");
sendBroadcast(i);

}
});
}
}

why I am not getting intent on AppA.... ?Can anyone help me on this.

onLongClickListener is driving me batshit crazy

Mind — 2013-05-17T14:05:10

I have two activities.  Each activity has a viewpager.  The adapter for 
each viewpager instantiates a number of views.

One of the views (let's call it ViewA) is a custom listview which populates 
itself with data from the internet.  ViewA is instantiated in each 
Activity's ViewPager's Adapter and shown correctly.  It pulls data from the 
internet and updates its display correctly.   ViewA also includes a 
onLongClickListener, which is added to each row in the ListView by the 
ListView's adapter.


Now this is the batshit crazy part.   In Activity 1, the 
onLongClickListener works.  In Activity 2, it does not get called.  However 
both ViewPager's Adapters instantiate ViewA (which is fully self contained).

For debugging, I can directly overlay a onLongClickListener after ViewA 
instantiation in the ViewPager Adapter, and that works.  However, lower 
down in my custom view, it never recieves the longClick... but ONLY when 
instantiatiated in Activity 2.  Activity1 works fine.


Hopefully this makes sense to someone and you can give me some pointers on 
how to debug this ?

No Intent to selection Contact Groups ?

Deepwinter — 2013-05-17T10:08:44

Is it necessary to code a custom activity to select a group of contacts? 
 Is there no build in activity that can handled ACTION_PICK for  

Groups.CONTENT_URI?  Does anyone have an open source recommendation for 
this?  Certainly wouldn't be hard to implement, just seems like something 
that's probably been done before.

Error installing Android Studio Preview version

Matt Kevins — 2013-05-16T19:50:29

I am following the instructions for installing Android Studio Preview on 
Linux. I am running Ubuntu 12.10 64 bit. This is the specific message I got:

'tools.jar' is not in the Android Studio classpath.


I then tried:

export JAVA_HOME=/usr/lib/jvm/default-java


based on advice on askubuntu.com, to no avail. Does anyone know what the 
issue might be, or how I can go resolving this? I would really like to try 
out Android Studio, since it looks really cool based on the presentation 
during the IO keynote.

Phone does not update an app from google store

gt8887b — 2013-05-16T17:26:39

Hello,

I am experiencing a strange issue with one of my customers.  Their Android 
phone does not download updates from the google play store.

They have PlayStore app configured to "Auto-update apps at any time." 
 However, even though the new update is online it would not install it for 
some reason.  

I am noticing on my own phone that some applications are not auto-updating 
either.  I have the same setting "Auto-update apps at any time." set but 
there are a few apps (YouTube, TeleNav GPS, Expedia app, etc.) that show up 
under "Manual Updates" in the play store app and would not update 
automatically.

Do you know what the reason may be?

Thank you.

Losing OpenGL context when home button is pressed! How to fix?

reaktor24 — 2013-05-16T12:13:28

I am trying to fix my apps OpenGL context loss whe the home button is 
pressed or when a call is received. How do I retreive the previous OpenGL 
states?? I am using OpenGL ES 2 and make sure to reload all the textures 
when a SurfaceCreated() is detected but it still isn't working. I assume I 
have to reload my shaders in the SurfaceCreated() and do I have to recall 
things like glViewport()?? Because all I am getting at the moment is a 
black screen. My shaders were moved to where the textures are loaded (as 
static objects) but unfortunately they don't work when I try to assign 
matrix handles to the shaders. I get java io exception errors. Null pointer 
exception etc. Will fixing this problem fix the overall context loss 
issue?? Thanks for your help.

ListView with "selected" state does not work when list item view has a background

Miha — 2013-05-16T09:14:29

Hi!

I'm trying to understand the mechanics behind "highlighting" the "selected" 
list item. I have a list fragment, which might display with a secondary 
"details fragment" if the screen width allows it. In that case, I want to 
highlight the selected list item. In order to do so, the listview has 
defined choice mode of single, and also a defined selector:

listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
listView.setSelector(R.drawable.listitem_selector);

The list uses a custom view for layout, and when the view does not set the 
"android:background", the listitem_selector works -- it shows on the 
screen. When the row layout has a background set to a drawable (in my case, 
it is selector, consisting of colors), the listitem_selector does not work. 
I tried the methods explained in the stackoverflow post<http://stackoverflow.com/questions/2562051/listview-item-background-via-custom-selector>, 
but the approach does not work, at least not in my case.

I'm obviously missing a part of the puzzle and I would appreciate any 
insight into this matter.

One possible solution I see is modifying the backing adapter implementation 
and providing a different view based on the state of the item, but that 
seems like wrong approach -- I would have to update the adapter with 
information on the selected item and call notifyDataSetChanged, which would 
(I suppose) result in an unnecessary re-drawing of the whole list.

Regards,
 Miha.
