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
            );
        }
    }
