I got solution for this question.
I have cracked code AOSP framework level(android.content.pm) and signed as a ploatform apk …
Finally app is silently uninstalling…
or
String cmd = “sh /system/bin/pm uninstall ” + packageName;
try {Process su = Runtime.getRuntime().exec("su");
DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());
outputStream.writeBytes(cmd+"\n");
outputStream.flush();
outputStream.writeBytes("exit\n");
outputStream.flush();
su.waitFor();
} catch (IOException e) {
throw new RuntimeException(e);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
solved Uninstall android application with out user interaction
