Plz check below classe & give me the suggestion for how to use them https://developer.android.com/reference/android/content/pm/PackageInstaller.html https://developer.android.com/reference/android/content/pm/PackageInstaller.Session.html
So please give me an example to install/update/remove app. Can it be possible that the new application will install in device profile owner?
It is possible without System permissions from Android M onwards.
if ((mPm.checkUidPermission(android.Manifest.permission.INSTALL_PACKAGES, installerUid)
== PackageManager.PERMISSION_GRANTED)
|| (installerUid == Process.ROOT_UID)
|| mIsInstallerDeviceOwner) {
mPermissionsAccepted = true;
} else {
mPermissionsAccepted = false;
}
Silent install and uninstall of apps by Device Owner:
A Device Owner can now silently install and uninstall applications using the PackageInstaller APIs, independent of Google Play for Work.
This is possible from Android 6.0 and up.
Once your app gets the Device owner permission, we can install, uninstall and update silently without any user intervention.
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();
}
Uninstall:
String appPackage = "com.your.app.package";
Intent intent = new Intent(getActivity(), getActivity().getClass());
PendingIntent sender = PendingIntent.getActivity(getActivity(), 0, intent, 0);
PackageInstaller mPackageInstaller = getActivity().getPackageManager().getPackageInstaller();
mPackageInstaller.uninstall(appPackage, sender.getIntentSender());
