Android： 判断某个应用中是否还有某个权限

1、如下代码需要更改的为getPackageInfo(value1,value2)的第一个参数value1，此参数为目标app的包名(packageName)；
2、需捕获PackageManager.NameNotFoundException的异常


PackageManager pm = getPackageManager();
try {
    PackageInfo pi = pm.getPackageInfo("com.android.contacts", PackageManager.GET_PERMISSIONS);
    String[] permissions = pi.requestedPermissions;
    for (String permission : permissions) {
        Log.i(TAG, "Contacts has :" + permission); //获取app含有权限
        if (permission.equals(CALL_PHONE)) {
            Log.i(TAG, "Contacts has CALL_PHONE permission --->" + permission); //判断某个权限是否存在

        }
    }
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}
