Android 接收微信、QQ其他应用打开,第三方分享

这里给大家分享我在网上总结出来的一些知识,希望对大家有所帮助

在AndroidManifest.xml注册ACTION事件

<activity
 android:name="com.test.app.MainActivity"
 android:configChanges="orientation|keyboardHidden|screenSize"
 android:label="这里的名称会对外显示"
 android:launchMode="singleTask"
 android:screenOrientation="portrait">
 //注册接收分享
 <intent-filter>
 <action android:name="android.intent.action.SEND" />
 <category android:name="android.intent.category.DEFAULT" />
 //接收分享的文件类型
 <data android:mimeType="image/*" />
 <data android:mimeType="application/msword" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" />
 <data android:mimeType="application/vnd.ms-excel" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" />
 <data android:mimeType="application/vnd.ms-powerpoint" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" />
 <data android:mimeType="application/pdf" />
 <data android:mimeType="text/plain" />
 </intent-filter>
 
 //注册默认打开事件,微信、QQ的其他应用打开
 <intent-filter>
 <action android:name="android.intent.action.VIEW" />
 <category android:name="android.intent.category.DEFAULT" />
 
 //接收打开的文件类型
 <data android:scheme="file" />
 <data android:scheme="content" />
 <data android:mimeType="image/*" />
 <data android:mimeType="application/msword" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" />
 <data android:mimeType="application/vnd.ms-excel" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" />
 <data android:mimeType="application/vnd.ms-powerpoint" />
 <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" />
 <data android:mimeType="application/pdf" />
 <data android:mimeType="text/plain" />
 </intent-filter>
 </activity>

在用于接收分享的Activity里面加接收代码

  1. 当APP进程在后台时,会调用Activity的onNewIntent方法
  2. 当APP进程被杀死时,会调用onCreate方法

所以在两个方法中都需要监听事件

@Override
 protected void onCreate(@Nullable Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 receiveActionSend(intent);
 }
 
 @Override
 protected void onNewIntent(Intent intent) {
 super.onNewIntent(intent);
 receiveActionSend(intent);
 }

receiveActionSend方法如下

public void receiveActionSend(Intent intent) {
 String action = intent.getAction();
 String type = intent.getType();
 //判断action事件
 if (type == null || (!Intent.ACTION_VIEW.equals(action) && !Intent.ACTION_SEND.equals(action))) {
 return;
 }
 
 //取出文件uri
 Uri uri = intent.getData();
 if (uri == null) {
 uri = intent.getParcelableExtra(Intent.EXTRA_STREAM);
 }
 
 //获取文件真实地址
 String filePath = UriUtils.getFileFromUri(EdusohoApp.baseApp, uri);
 if (TextUtils.isEmpty(filePath)) {
 return;
 }
 //业务处理
 .
 .
 .
 }

获取真实路径getFileFromUri方法

/**
 * 获取真实路径
 *
 * @param context
 */
 public static String getFileFromUri(Context context, Uri uri) {
 if (uri == null) {
 return null;
 }
 switch (uri.getScheme()) {
 case ContentResolver.SCHEME_CONTENT:
 //Android7.0之后的uri content:// URI
 return getFilePathFromContentUri(context, uri);
 case ContentResolver.SCHEME_FILE:
 default:
 //Android7.0之前的uri file://
 return new File(uri.getPath()).getAbsolutePath();
 }
 }

Android7.0之后的uri content:// URI需要对微信、QQ等第三方APP做兼容

  • 在文件管理选择本应用打开时,url的值为content://media/external/file/85139
  • 在微信中选择本应用打开时,url的值为 content://com.tencent.mm.external.fileprovider/external/tencent/MicroMsg/Download/111.doc
  • 在QQ中选择本应用打开时,url的值为 content://com.tencent.mobileqq.fileprovider/external_files/storage/emulated/0/Tencent/QQfile_recv/

第一种为系统统一文件资源,能通过系统方法转化为绝对路径;
微信、QQ的为fileProvider,只能获取到文件流,需要先将文件copy到自己的私有目录。
方法如下:

/**
 * 从uri获取path
 *
 * @param uri content://media/external/file/109009
 * <p>
 * FileProvider适配
 * content://com.tencent.mobileqq.fileprovider/external_files/storage/emulated/0/Tencent/QQfile_recv/
 * content://com.tencent.mm.external.fileprovider/external/tencent/MicroMsg/Download/
 */
 private static String getFilePathFromContentUri(Context context, Uri uri) {
 if (null == uri) return null;
 String data = null;
 String[] filePathColumn = {MediaStore.MediaColumns.DATA, MediaStore.MediaColumns.DISPLAY_NAME};
 Cursor cursor = context.getContentResolver().query(uri, filePathColumn, null, null, null);
 if (null != cursor) {
 if (cursor.moveToFirst()) {
 int index = cursor.getColumnIndex(MediaStore.MediaColumns.DATA);
 if (index > -1) {
 data = cursor.getString(index);
 } else {
 int nameIndex = cursor.getColumnIndex(MediaStore.MediaColumns.DISPLAY_NAME);
 String fileName = cursor.getString(nameIndex);
 data = getPathFromInputStreamUri(context, uri, fileName);
 }
 }
 cursor.close();
 }
 return data;
 }
 
 /**
 * 用流拷贝文件一份到自己APP私有目录下
 *
 * @param context
 * @param uri
 * @param fileName
 */
 private static String getPathFromInputStreamUri(Context context, Uri uri, String fileName) {
 InputStream inputStream = null;
 String filePath = null;
 if (uri.getAuthority() != null) {
 try {
 inputStream = context.getContentResolver().openInputStream(uri);
 File file = createTemporalFileFrom(context, inputStream, fileName);
 filePath = file.getPath();
 } catch (Exception e) {
 } finally {
 try {
 if (inputStream != null) {
 inputStream.close();
 }
 } catch (Exception e) {
 }
 }
 }
 return filePath;
 }
 private static File createTemporalFileFrom(Context context, InputStream inputStream, String fileName)
 throws IOException {
 File targetFile = null;
 if (inputStream != null) {
 int read;
 byte[] buffer = new byte[8 * 1024];
 //自己定义拷贝文件路径
 targetFile = new File(context.getExternalCacheDir(), fileName);
 if (targetFile.exists()) {
 targetFile.delete();
 }
 OutputStream outputStream = new FileOutputStream(targetFile);
 while ((read = inputStream.read(buffer)) != -1) {
 outputStream.write(buffer, 0, read);
 }
 outputStream.flush();
 try {
 outputStream.close();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
 return targetFile;
 }
