BitmapFactory.decodeFile始终为null的

问题描述

Android从相册中选择照片时选完后显示不出来，打断点发现srcPath图片路径正确，bitmap竟然为空😺‘。

bitmap = BitmapFactory.decodeFile(srcPath, opts); 

检查一下👀：

• opts属性没问题

opts.inJustDecodeBounds = false;

• AndroidManifest中权限申请，没问题

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

• 动态权限申请

private static final String[] PERMISSION_EXTERNAL_STORAGE = new String[] {
      Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE
  };
  private static final int REQUEST_EXTERNAL_STORAGE = 100;
......
private void verifyStoragePermissions(Activity activity) {
    int permissionWrite = ActivityCompat.checkSelfPermission(activity,
        Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (permissionWrite != PackageManager.PERMISSION_GRANTED) {
      ActivityCompat.requestPermissions(activity, PERMISSION_EXTERNAL_STORAGE,
          REQUEST_EXTERNAL_STORAGE);
    }
  }

• 竟然还是不行🐶，我接着找🥱
  最后看到一篇帖子讲需要在AndroidManifest.xml中添加android:requestLegacyExternalStorage="true"
  原因如下(拷图过来，链接https://www.freesion.com/article/3094311913/):
