本文實例講述了Android編程實現監控apk安裝，卸載，替換的方法。分享給大家供大家參考，具體如下：
public class GetBroadcast extends BroadcastReceiver { private static GetBroadcast mReceiver = new GetBroadcast(); private static IntentFilter mIntentFilter; public static void registerReceiver(Context context) { mIntentFilter = new IntentFilter(); mIntentFilter.addDataScheme("package"); mIntentFilter.addAction(Intent.ACTION_PACKAGE_ADDED); mIntentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED); mIntentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED); context.registerReceiver(mReceiver, mIntentFilter); } public static void unregisterReceiver(Context context) { context.unregisterReceiver(mReceiver); } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (Intent.ACTION_PACKAGE_ADDED.equals(action)) { Toast.makeText(context, "有應用被添加", Toast.LENGTH_LONG).show(); } else if (Intent.ACTION_PACKAGE_REMOVED.equals(action)) { Toast.makeText(context, "有應用被刪除", Toast.LENGTH_LONG).show(); } /* * else if(Intent.ACTION_PACKAGE_CHANGED.equals(action)){ * Toast.makeText(context, "有應用被改變", Toast.LENGTH_LONG).show(); } */ else if (Intent.ACTION_PACKAGE_REPLACED.equals(action)) { Toast.makeText(context, "有應用被替換", Toast.LENGTH_LONG).show(); } /* * else if(Intent.ACTION_PACKAGE_RESTARTED.equals(action)){ * Toast.makeText(context, "有應用被重啟", Toast.LENGTH_LONG).show(); } */ /* * else if(Intent.ACTION_PACKAGE_INSTALL.equals(action)){ * Toast.makeText(context, "有應用被安裝", Toast.LENGTH_LONG).show(); } */ }}希望本文所述對大家Android程序設計有所幫助。
