二、解决问题

• AndroidManifest.xml

    <application
    	
		<provider
		    android:name="android.support.v4.content.FileProvider"
		    android:authorities="com.lisi.evidence_box.provider"
		    android:exported="false"
		    android:grantUriPermissions="true">
		    <meta-data
		        android:name="android.support.FILE_PROVIDER_PATHS"
		        android:resource="@xml/provider_paths"/>
		</provider>
		
    </application>

• /res/xml/provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

• 【原本】Java源码

if (path.endsWith(".mp4")) {
    
    
    try {
    
    
        File f = new File(path);
        Uri uri = Uri.fromFile(f);

        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(uri, "video/*");
        startActivity(intent);
    } catch (ActivityNotFoundException e) {
    
    
        e.printStackTrace();
    }
}

• 【改成】Java源码

if (path.endsWith(".mp4")) {
    
    
    try{
    
    
        File f = new File(path);
        Uri contentUri = FileProvider.getUriForFile(getContext(), "com.your.package.provider", f);

        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        intent.setDataAndType(contentUri, "video/*");
        startActivity(intent);
    } catch (ActivityNotFoundException e) {
    
    
        e.printStackTrace();
    }
}

三、分析问题

Android N对访问文件权限收回，按照Android N的要求，若要在应用间共享文件，您应发送一项 content://URI，并授予 URI 临时访问权限。
