AndrodiManifest.xml文件中配置
<provider
android:name="com.soonfor.repository.view.Mdgj_ZskFileProvider"
android:authorities="com.soonfor.repository.mdgj_zffileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/rep_file_paths" />
</provider>
之后在资源文件夹中创建
rep_file_paths.xml文件,文件内容如下
<paths>
<external-path name="my_images" path="Pictures"/>
<external-path name="UcpFiles" path="UcpFiles/" />
</paths>
设置完成以上步奏调用以下代码就可以打开了
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(new File(path)).toString());
String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
//7.0以上需要
if (Build.VERSION.SDK_INT >= 24) {
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri uri = FileProvider.getUriForFile(context, "com.soonfor.repository.mdgj_zffileprovider", new File(path));
intent.setDataAndType(uri, mimetype);
} else {
intent.setDataAndType(Uri.fromFile(new File(path)), mimetype);
}
context.startActivity(intent);
