Android10+ 文件用其他方式打开或者分享打开添加自己App
萌新处文，水文一篇，大佬轻拍，大佬轻拍，大佬轻拍
需求比较少见，简单来说是可以在app内打开系统文件选择器，取到对应文件并上传(我这边为Excel，比较少)。同时需要支持在其他应用（文件选择器类）中选择发送/分享或者其他应用打开完成后续上传工作。
知识点在于
添加自己应用在打开/分享列表
兼容大部分返回的uri
Android用其他方式打开文件
此功能较为简单。
反编译市场上有此功能的软件，查看其对应xml配置可得到。下为对xls和xlsx文件响应。
ContentType 类型可百度找到
我的参考链接为：blog.csdn.net/u013749540/…
<!--分享/发送--> <intent-filter> <action android:name="android.intent.action.SEND"/> <action android:name="android.intent.action.SEND_MULTIPLE"/> <category android:name="android.intent.category.DEFAULT"/> <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /> <data android:mimeType="application/vnd.ms-excel" /> <data android:mimeType="text/comma-separated-values" /> </intent-filter> <!--在其他应用打开--> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <data android:scheme="file" /> <data android:scheme="content" /> <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /> <data android:mimeType="application/vnd.ms-excel" /> <data android:mimeType="text/comma-separated-values" /> </intent-filter>复制代码
另外有如声明具体功能的情况，如保存到XX，收藏到XX，可添加
``` <activity-alias android:name="com.ucpro.file" android:icon="@mipmap/launcher_ic" android:label="导入到XX" android:resizeableActivity="false" android:targetActivity=".ui.activity.HomeActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="file" /> <data android:scheme="content" /> <data android:mimeType="*/*" /> <data android:pathPattern=".*.*" /> </intent-filter> ```复制代码
兼容大部分返回的Uri的工具类
我目前看到的不同机子不用情况下返回的uri有：
/external/file/11611
/external_files/Download/xxxx
content://com.android.providers.media.documents/document/document:127686
content://com.android.providers.downloads.documents/document/msf:3A127686
/root/storage/emulated/0/android/data/xxxx
.......
另外，Android11 在QQ浏览器或者微信会话使用没法使用第三方打开，其路径为
/QQBrowser/Android/data/com.tencent.mtt/files/.ReaderTemp/thrdcall/contenturi/xxxx
/external/Android/data/com.tencent.mm/MicroMsg/Download/xxxx
Android11储存更新：developer.android.google.cn/about/versi…
所以无法获取到Android/data/下的文件，目前解决方式为引导用户操作????
有大佬能适配这种情况的，求指点下
根据Uri获取真实FilePath参考实现：stackoverflow.com/questions/1…
工具类代码：
public class FilePathUtils {
/**
* <p>
* 获取完整文件名(包含扩展名)
*
* @param filePath
* @return
*/
public static String getFilenameWithExtension(String filePath) {
if (filePath == null || filePath.length() == 0) {
return "";
}
int lastIndex = filePath.lastIndexOf(File.separator);
String filename = filePath.substring(lastIndex + 1);
return filename;
}
/**
* 判断文件路径的文件名是否存在文件扩展名 eg: /external/images/media/2283
*
* @param filePath
* @return
*/
public static boolean isFilePathWithExtension(String filePath) {
String filename = getFilenameWithExtension(filePath);
return filename.contains(".");
}
/**
* 判断文件路径的文件名是否存在文件扩展名 eg: /external/images/media/2283
*
* @param context
* @param uri
* @return
*/
@RequiresApi(api = Build.VERSION_CODES.Q)
public static String getPathFromUri(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
// TODO handle non-primary volumes
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
/* 文件浏览器的下载返回的uri为
* content://com.android.providers.downloads.documents/document/msf:3A127686
* Android10以上，getDataColumn中的uri为 MediaStore.Downloads.EXTERNAL_CONTENT_URI
*/
if (id.startsWith("msf:")) {
final String[] split = id.split(":");
final String selection = "_id=?";
final String[] selectionArgs = new String[]{split[1]};
return getDataColumn(context, MediaStore.Downloads.EXTERNAL_CONTENT_URI, selection, selectionArgs);
} else {
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
/*
* 由于是文档类型，所以记得加上document判断，具体的MediaStore项我没有找到，有大佬知道的话，求指点下
* */
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
} else if ("document".equals(type)) {
contentUri = MediaStore.Downloads.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[]{
split[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
// Return the remote address
if (isGooglePhotosUri(uri)) {
return uri.getLastPathSegment();
}
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection,
String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(index);
}
} finally {
if (cursor != null) {
cursor.close();
}
}
return null;
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is ExternalStorageProvider.
*/
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is DownloadsProvider.
*/
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is MediaProvider.
*/
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());

* @return Whether the Uri authority is Google Photos.
*/
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
}复制代码工具类的使用：
文件浏览器回调
startActivityForResult(intent, (resultCode, data) -> {
if (resultCode == Activity.RESULT_OK && data != null) {
Uri uri = data.getData();
if (uri != null) {
File file;
/*
*判断有无文件拓展名，有则直接调用 http://blankj.com 大神的工具箱，无则表示为content形式调用自己的工具类
* */
if (FilePathUtils.isFilePathWithExtension(uri.getPath())) {
file = UriUtils.uri2File(uri);
} else {
file = FileUtils.getFileByPath(FilePathUtils.getPathFromUri(getContext(), uri));
}
uploadFile(file);
}
}
});
}复制代码发送/分享，打开也差不多就不反复贴了。
@SuppressLint("ObsoleteSdkInt")
@RequiresApi(api = Build.VERSION_CODES.Q)
private void getShareFromOthers() {
//分享/发送
Intent shareIntent = getIntent();
String action = shareIntent.getAction();
String type = shareIntent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet".equals(type) || "application/vnd.ms-excel".equals(type)) {
Uri uri2 = shareIntent.getParcelableExtra(Intent.EXTRA_STREAM);
if (uri2 != null) {
String host = uri2.getHost();
String dataString = shareIntent.getDataString();
String path = uri2.getPath();
String path1 = uri2.getEncodedPath();
/* 华为文件管理器根目录会以/root/storage/emulated/0/方式传，手动剔除/root*/
if (path.startsWith(getString(R.string.file_root))){
path=path.substring(5);
}
if (excelShareInput) {
File file;
/* 判断是否文件是否有后缀*/
if(FilePathUtils.isFilePathWithExtension(path)){
/* 小米Android11返回为/external_files/xxx,将其替换*/
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
path = path.replace(getString(R.string.file_storage), PathUtils.getExternalStoragePath());
file = FileUtils.getFileByPath(path);
Timber.d("file = %s", file);
} else {
file = FileUtils.getFileByPath(path);
}
}else {
/* 由content获取真实路径*/
file =FileUtils.getFileByPath(FilePathUtils.getPathFromUri(getContext(),uri2));
}
}
}
}
}复制代码写到这里。文件用其他方式打开或者分享打开添加自己App和App内找对文件上传算是完事了。当然后面如果有更多的适配方案还会继续补充。????
