我也检查了带有 URI:content://com.funfil.provider.OCR/funfildata 的应用程序。

我将一个新活动称为

startActivity(new Intent(Intent.ACTION_INSERT, getIntent().getData()));

Answer 1

如果您想使用一组特定的 uri 启动活动，则必须在清单文件中使用 scheme 定义您的活动：

<intent-filter . . . >
    <data android:scheme="content" android:host"com.funfil.provider.OCR" />
</intent-filter>

Answer 2

检查您的 ContentProvider 的 getType("content://com.funfil.provider.OCR/funfildata/") 是否返回 vnd.android.cursor.dir/vnd.funfil.funfildata
