系統(tǒng)相冊做兼容性測試的時候，遇到神坑手機Redmi Note4。

先上調(diào)用的代碼：

//調(diào)用相冊
 private void go2Gallery() {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("image/*");
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

在其他手機都能正確的打開相冊，但是在這個手機會出現(xiàn)下面這個截圖

然后點擊相冊，沒有任何反應，看了log也沒有任何的報錯，然后就開始各種百度使用了下面的調(diào)用方式：

//調(diào)用相冊
 private void go2Gallery() {
        Intent intent = new Intent();
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.setType("image/*");
        if (Build.VERSION.SDK_INT < 19) {
            intent.setAction(Intent.ACTION_GET_CONTENT);
        } else {
            intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
        }
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

懷著即將解決的心情，打開測試手機，尼瑪這次直接打開的是個樹形的文件管理器。內(nèi)心奔潰中，差點懷疑人生。然后對比了前面的兩個方法，無非就是intent的action不一樣，然后就接著百度終于還有一個action叫做Intent.ACTION_PICK。然后換了下面的代碼：

//調(diào)用相冊
  private void go2Gallery() {
        Intent intent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }

哎呀媽呀，終于成了，然后又試了試其它的手機，包括6.0,7.0的Android手機，都正常。問題總算是解決了。

下面是完整的代碼，僅供參考~

//調(diào)用系統(tǒng)相機
 private void doTakePhoto() {
        mCurrentPhotoFile = new File(yourpath);
        if (!mCurrentPhotoFile.exists()) {
            try {
                mCurrentPhotoFile.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE, null);
        intent.putExtra(MediaStore.EXTRA_OUTPUT,
                Uri.fromFile(mCurrentPhotoFile));
        try {
            startActivityForResult(intent, CAMERA_WITH_DATA);
        } catch (ActivityNotFoundException e) {
            e.printStackTrace();
        }
    }
    
    //調(diào)用系統(tǒng)相冊

        try {
            startActivityForResult(intent, PICK_IMAGE_DATA);
        } catch (ActivityNotFoundException e) {

        }
    }
    
    
      @Override

        if (resultCode == Activity.RESULT_OK) {

               Uri uri = data.getData();
                if (uri != null) {
                String path = Util.getGoogleImagePath(mActivity, uri); 
                //...do your code

    }
