FileNotFoundException:EACCES (permission denied) Android10

需要在三个地方添加权限获取代码，如下

 

1、AndroidManifest.xml 中

1）添加  uses-permission 

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<!-- 在SDCard中创建与删除文件权限 -->
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
    tools:ignore="ProtectedPermissions" />
<!-- 往SDCard写入数据权限 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    tools:ignore="ScopedStorage" />

2）< application 中添加

android:requestLegacyExternalStorage="true"


2、mainActivity中添加请求权限

private void getPermission() {     int REQUEST_EXTERNAL_STORAGE = 1;     String[] PERMISSIONS_STORAGE = {             Manifest.permission.READ_EXTERNAL_STORAGE,             Manifest.permission.WRITE_EXTERNAL_STORAGE     };     int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);       if (permission != PackageManager.PERMISSION_GRANTED) {         // We don't have permission so prompt the user         ActivityCompat.requestPermissions(                 MainActivity.this,                 PERMISSIONS_STORAGE,                 REQUEST_EXTERNAL_STORAGE         );     } }
