Android使用BroadCastReceiver阻止传入的SMS

检查您的应用程序是否正在运行，然后仅中止广播接收器，否则不运行

//define this variable above onReceive() with default value as false;boolean appRunningInBack=false;ActivityManager am = (ActivityManager) mContext.getSystemService(Activity.ACTIVITY_SERVICE);String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();if(packageName.equalIgnoreCase("your app package name") || appRunningInBack){        appRunningInBack=true;    abortBroadCast();} else {}

Also add Permission in AndroidManifest.xml

<uses-permission android:name="android.permission.GET_TASKS" />

之后，当您的应用进入后台或运行时，此变量将为true。
