推荐答案

您可以注册广播意图 Intent.ACTION_PACKAGE_ADDED （和/或意图。 ACTION_PACKAGE_REMOVED ， Intent.ACTION_PACKAGE_CHANGED 如果需要的话）。

You can register Broadcast intent Intent.ACTION_PACKAGE_ADDED ( and/or Intent.ACTION_PACKAGE_REMOVED, Intent.ACTION_PACKAGE_CHANGED if needed).

code是类似以下内容：

Code is something like following:

void registerReceiver() {
    IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
    filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
    filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
    filter.addDataScheme("package");
    ...
}

public void onReceive(Context context, Intent intent) {
    String actionStr = intent.getAction();
    if (Intent.ACTION_PACKAGE_ADDED.equals(actionStr)) {
        Uri data = intent.getData();
        String pkgName = data.getEncodedSchemeSpecificPart();
        //handle package adding...
    ...
    }
}
