compileSdkVersion 30及以上文件读取失败，open failed: EACCES (Permission denied)

Android 11 将强制执行分区存储，Android 无法创建和访问自定义目录

SDK29代表支持在安卓10上运行
SDK30代表支持在安卓11上运行

compileSdkVersion 30及以上android:requestLegacyExternalStorage="true"也不起作用

 

暂时方案就是compileSdkVersion 改为29及以下，

然后加上android:requestLegacyExternalStorage="true"

 

外加读写权限

 

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
