        String action = intent.getAction();

        Uri uri = intent.getData();

        if ("android.intent.action.PACKAGE_ADDED".equals(action)) {
            Toast.makeText(context, "有应用被安装:" + uri.toString(), Toast.LENGTH_SHORT).show();
        } else if ("android.intent.action.PACKAGE_REPLACED".equals(action)) {
