android 监听安装状态,BroadcastReceiver几种常见监听详解

1.BroadcastReceiver监听拨号

@Override

public void onReceive(Context context, Intent intent) {

//获取拨打电话的号码

String call=getResultData();

//在电话号码前加上110，然后返回数据

setResultData("110"+call);

}

2.BroadcastReceiver监听短信

3.BroadcastReceiver监听SD卡状态

public class SDStatusReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

//判断收到的到底是什么广播

String action = intent.getAction();

if("android.intent.action.MEDIA_MOUNTED".equals(action)){

Toast.makeText(context, "SD卡可用", 0).show();

}

else if("android.intent.action.MEDIA_REMOVED".equals(action)){

Toast.makeText(context, "SD卡拔出", 0).show();

}

else if("android.intent.action.MEDIA_UNMOUNTED".equals(action)){

Toast.makeText(context, "SD卡不可用", 0).show();

}

}

}

4.BroadcastReceiver监听开机

5.BroadcastReceiver监听应用安装卸载

public class IntallReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String packageName = intent.getData().toString();

String action = intent.getAction();

// 如果是卸载

if ("android.intent.action.PACKAGE_REMOVED".equals(action)) {

Toast.makeText(context, packageName+"应用程序被卸载", 1).show();

System.out.println(packageName+"已删除");

} else if ("android.intent.action.PACKAGE_ADDED".equals(action)) {

Toast.makeText(context, packageName+"应用程序安装", 1).show();

System.out.println(packageName + "已安装");

}

}

}
