I know there is many stack-overflow posts for this question, but i couldn't solve my problem using any of them.
My app is only available for a limited group of people(inner company app), so i can't publish it in an app store and i want it to be updated automatically when i release a new version on the app server.
it is a device admin app with no root permission. i found this approach to achieve this goal but it didn't work.
I have this permission in my AndroidManifest.xml file to install packages:
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
This is my code:
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void installPackage(Context context, String filePath, String packageName)
throws IOException
{
Log.d(TAG, "installPackage: start");
PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
PackageInstaller.SessionParams.MODE_FULL_INSTALL);
params.setAppPackageName(packageName);
// set params
int sessionId = packageInstaller.createSession(params);
PackageInstaller.Session session = packageInstaller.openSession(sessionId);
//
InputStream in = new FileInputStream(new File(filePath));
OutputStream out = session.openWrite(packageName, 0, -1);
IOUtils.copyStream(in, out);
//
session.fsync(out);
in.close();
out.close();
//
session.commit(PendingIntent.getActivity(context, 112233, new Intent(context, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT).getIntentSender());
Log.d(TAG, "installPackage: commit");
}
And this is onCreate method of my MainActivity class:
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
ComponentName componentName = new ComponentName(this, AdminReceiver.class);
DevicePolicyManager dpm = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
if (getIntent() != null && dpm != null)
{
Log.d(TAG, "onCreate: is app admin : " + dpm.isAdminActive(componentName));
Log.d(TAG, "onCreate: status : " + getIntent().getIntExtra("android.content.pm.extra.STATUS", 1000));
Log.d(TAG, "onCreate: intent : " + getIntent().getParcelableExtra("android.intent.extra.INTENT"));
}
}
and this is my logcat result :

Here, as we see, status is -1. according to this document i got STATUS_PENDING_USER_ACTION and it determine we need user prompt to update our app.but this app is a device admin(device owner) app and according to this document:
Committing may require user intervention to complete the installation, unless the caller falls into one of the following categories, in which case the installation will complete automatically.
- the device owner
- the affiliated profile owner
so if app be device owner install progress will perform automatically (with out user prompt). then why do i get STATUS_PENDING_USER_ACTION while my app is a device admin app?
