Is it possible to install an APK once the application has become device admin. I tried installing package using the code below but it didn't work.
private static final String ACTION_INSTALL_COMPLETE = "com.test.sampleapp_dev.INSTALL_COMPLETE";
public static boolean installPackage(Context context, InputStream in, String packageName)
throws IOException {
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);
OutputStream out = session.openWrite("COSU", 0, -1);
byte[] buffer = new byte[65536];
int c;
while ((c = in.read(buffer)) != -1) {
out.write(buffer, 0, c);
}
session.fsync(out);
in.close();
out.close();
session.commit(createIntentSender(context, sessionId));
return true;
}
private static IntentSender createIntentSender(Context context, int sessionId) {
PendingIntent pendingIntent = PendingIntent.getBroadcast(
context,
sessionId,
new Intent(ACTION_INSTALL_COMPLETE),
0);
return pendingIntent.getIntentSender();
}
The Device Admin cannot silently install apps. Only the Device Owner can silently install apps.
To set the app as the device owner, use one of the following options:
dpm set-device-owner com.yourpackage.id/.AdminReceiver
You must first implement the BroadcastReceiver which receives the event of being the Device Owner. You can look for the sample code here: https://github.com/h-mdm/hmdm-android (this is my open source MDM project).
