当前,当文件位于外部SD卡上时,FileProvider的getUriForFile方法会生成IllegalArgumentException异常。 当文件位于设备内存中(在/storage/emulated/0下)时,则能正常工作。
Uri videoUri = FileProvider.getUriForFile(this,
getApplicationContext().getPackageName() + ".provider",
new File(videoPath));
此处videoPath的值为:
videoPath = /storage/extSdCard/Android/data/com.podcastcutter.debug/files/episodeMp3/TEDTalks (video)/Why you should love statistics - Alan Smith.mp4
我的清单文件包含:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
这里是 provider_paths:
<external-path name="external_files" path="."/>
如何修改FileProvider配置以解决这个问题?
提前致谢。
生成的异常:
java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/extSdCard/Android/data/com.podcastcutter.debug/files/episodeMp3/TEDTalks (video)/Why you should love statistics - Alan Smith.mp4
