Delete my application programmatically (Android)

Question

I want to uninstall my application on button click. For this I am using following code.

Uri packageURI = Uri.parse("package:"+packageName);
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);

It gives me result, but I want to delete directly without click on "Ok" button of dialog with message "This application will be Uninstalled".

I just want uninstalling application directly.

Answer 1

Uninstalling without user confirmation is not allowed to 3rd party applications.

As xDragonZ points out, a root process can crudely do this by literally removing the directory and leaving the package manager to deal with the loss, but that's not a very widely deployable solution, since AFAIK no devices ship with that capability for apps to run their own root helper process - that's a risky aftermarket modification.

Yes it is possible to uninstall a package in Android. Moreover you can also skip asking user to press OK button on uninstall screen. You can do it by using Accessibility service in Android.

public class MyAccessibilityService extends AccessibilityService {
    private static final String TAG = MyAccessibilityService.class
            .getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType());

        //TYPE_WINDOW_STATE_CHANGED == 32
        if (AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED == event
                .getEventType()) {
            AccessibilityNodeInfo nodeInfo = event.getSource();
            Log.i(TAG, "ACC::onAccessibilityEvent: nodeInfo=" + nodeInfo);
            if (nodeInfo == null) {
                return;
            }

            List<AccessibilityNodeInfo> list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("com.android.settings:id/left_button");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: left_button " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }

            list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("android:id/button1");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: button1 " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }
        }

    }

    @Override
    public void onServiceConnected() {
        Log.i(TAG, "ACC::onServiceConnected: ");
    }

    @Override
    public void onInterrupt() {
        // TODO Auto-generated method stub

    }
}
