Android监听程序的安装和卸载

在android系统中，安装和卸载都会发送广播，当应用安装完成后系统会发android.intent.action.PACKAGE_ADDED广播。可以通过intent.getDataString()获得所安装的包名。当卸载程序时系统发android.intent.action.PACKAGE_REMOVED广播。同样intent.getDataString()获得所卸载的包名

应用程序无法监听自己的安装与卸载，但覆盖安装可以监听到自己的android.intent.action.PACKAGE_REMOVED广播。

这里是手动注册广播

public class GetBroadcast extends BroadcastReceiver {
02

03
private static GetBroadcast mReceiver = new GetBroadcast();
04
private static IntentFilter mIntentFilter;
05

06

07
public static void registerReceiver(Context context) {
08
mIntentFilter = new IntentFilter();
09
mIntentFilter.addDataScheme(“package”);
10
mIntentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
11
mIntentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED);
12
mIntentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED);
13
context.registerReceiver(mReceiver, mIntentFilter);
14
}
15

16
public static void unregisterReceiver(Context context) {
17
context.unregisterReceiver(mReceiver);
18
}
19

20
@Override
21
public void onReceive(Context context, Intent intent) {
22
String action = intent.getAction();
23
if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
24
Toast.makeText(context, “有应用被添加”, Toast.LENGTH_LONG).show();
25
} else if (Intent.ACTION_PACKAGE_REMOVED.equals(action)) {
26
Toast.makeText(context, “有应用被删除”, Toast.LENGTH_LONG).show();
27
}
28

29
/*
30
* else if(Intent.ACTION_PACKAGE_CHANGED.equals(action)){
31
* Toast.makeText(context, “有应用被改变”, Toast.LENGTH_LONG).show(); }
32
*/
33

34
else if (Intent.ACTION_PACKAGE_REPLACED.equals(action)) {
35
Toast.makeText(context, “有应用被替换”, Toast.LENGTH_LONG).show();
36
}
37

38
/*
39
* else if(Intent.ACTION_PACKAGE_RESTARTED.equals(action)){
40
* Toast.makeText(context, “有应用被重启”, Toast.LENGTH_LONG).show(); }
41
*/
42

43
/*
44
* else if(Intent.ACTION_PACKAGE_INSTALL.equals(action)){
45
* Toast.makeText(context, “有应用被安装”, Toast.LENGTH_LONG).show(); }
