调用需要 API 级别 23（当前最低为 14）：android.app.Activity#requestPermissions,checkSelfPermission

Question

我正在尝试添加运行时间权限 android(6.0.1) API 23，如果我使用 SDK 版本（min 和目标版本都是 23 ) 效果很好，如下所示，

    <uses-sdk
                android:minSdkVersion="23"
                android:targetSdkVersion="23" />

如果我改变android:minSdkVersion（小于23）

例如：

我收到以下错误：

Call requires API level 23 (current min is 14): android.app.Activity#requestPermissions,checkSelfPermission

以下2种方法，

1)requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS)

2)checkSelfPermission(permission)

我试过 ActivityCompat.checkSelfPermission() 和 ContextCompat.checkSelfPermission() 都不起作用。

我想的没看懂..

Answer 1

调用请求权限前检查设备sdk

 if(Build.VERSION.SDK_INT==Build.VERSION_CODES.M)
{
//call the request permission here 
}

Answer 2

试试这个方法

if (Build.VERSION.SDK_INT >= 23) {
    if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            requestContactsPermissions1();
    } else {
        // your code
    }
}

已编辑：

在较低级别（您的应用程序）中添加依赖项块build.gradle：

compile 'com.android.support:appcompat-v7:23.1.1'

或仅在需要设计支持库时才在下面添加

compile 'com.android.support:design:23.1.1'

使用以上之一

Answer 3

那是因为在API23中添加了checkSelfPermission()。所以你必须有条件地编码：

if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M){
    //use checkSelfPermission()
} else {
    //simply use the required feature
    //as the user has already granted permission to them during installation
}

Answer 4

检查目标 >=23 或简单地在您的方法上方添加下面一行

@TargetApi(Build.VERSION_CODES.M)

比如你是检查存储权限，那么可以参考这个函数，

@TargetApi(Build.VERSION_CODES.M)
    public boolean CheckStoragePermission() {
        int permissionCheckRead = ContextCompat.checkSelfPermission(context,
                Manifest.permission.READ_EXTERNAL_STORAGE);
        if (permissionCheckRead != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context,
                    Manifest.permission.READ_EXTERNAL_STORAGE)) {
                // Show an expanation to the user *asynchronously* -- don't block
                // this thread waiting for the user's response! After the user
                // sees the explanation, try again to request the permission.
                ActivityCompat.requestPermissions((Activity) context,
                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                        Define.PERMISSION_STORAGE);
            } else {
                // No explanation needed, we can request the permission.

                ActivityCompat.requestPermissions((Activity) context,
                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                        Define.PERMISSION_STORAGE);

                // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
                // app-defined int constant. The callback method gets the
                // result of the request.
            }
            return false;
        } else
            return true;
    }

Answer 5

检查权限：

ContextCompat.checkSelfPermission(Context context, String permission)

请求权限：

ActivityCompat.requestPermissions(Activity activity, String[] permissions, int requestCode)

或在 support-v4 中 Fragment

requestPermissions(String[] permissions, int requestCode)

调用需要 API 级别 23（当前最低为 14）：android.app.Activity#requestPermissions,checkSelfPermission

Call requires API level 23 (current min is 14): android.app.Activity#requestPermissions,checkSelfPermission
