我已经从画廊创建了多选择器图像功能。它只能正常工作有时多选择器 Intent 活动没有启动，它显示“没有找到处理 Intent 的活动”错误任何人帮助我解决这个错误。但有时它工作正常。`

btnGalleryPickMul.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent i = new Intent(Action.ACTION_MULTIPLE_PICK);
                startActivityForResult(i, 200);
            }
        });

  @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 200 && resultCode == Activity.RESULT_OK) {
        String[] all_path = data.getStringArrayExtra("all_path");

        ArrayList<CustomGallery> dataT = new ArrayList<CustomGallery>();


        for (String string : all_path) {
            CustomGallery item = new CustomGallery();
            item.sdcardPath = string;

            dataT.add(item);
            //
            String size=item.sdcardPath;
            Log.d("size--", size);
            image1.add(item.sdcardPath);
            Log.d("map--", String.valueOf(image1));


            ArrayList<String> ImgData =image1;
            Log.d("ImgData--", String.valueOf(ImgData));


            for (int i = 0; i < ImgData.size(); i++) {
                map.add(ImgData.get(i).toString());


            }

        }

        viewSwitcher.setDisplayedChild(0);
        adapter.addAll(dataT);

        new ImageUploadTask()
                .execute(count + "", "pk" + count + ".jpg");
    }
}

【解决方案1】：

使用下面的函数创建 Intent 并检查它是否可用

public static boolean isAvailable(Context ctx, Intent intent) {
   final PackageManager mgr = ctx.getPackageManager();
   List<ResolveInfo> list =
      mgr.queryIntentActivities(intent, 
         PackageManager.MATCH_DEFAULT_ONLY);
   return list.size() > 0;
}

更新您的代码：

btnGalleryPickMul.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent i = new Intent(Action.ACTION_MULTIPLE_PICK);
                if(isAvailable(mContext,i))
                startActivityForResult(i, 200);
            }
        });
