解决Android调用系统分享给微信,出现分享失败,分享多文件必须为图片格式的问题

 private void systemShareWeChat(int shareTag,String photoPath){
    Resources res=getResources();
    Bitmap bmp=BitmapFactory.decodeResource(res, R.drawable.share);
    File f = null;

    ComponentName comp1,comp;
    comp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareImgUI");//调用系统分享给微信朋友
    comp1 = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareToTimeLineUI");//调用系统分享给微信朋友圈

    try {
    //将Android中drawable图片保存到本地
      String dir= Environment.getExternalStorageDirectory().getAbsolutePath() File.separator "share" ".jpg";
       f = new File(dir);
      if (!f.exists()) {
        f.getParentFile().mkdirs();
        f.createNewFile();
      }
      FileOutputStream out = new FileOutputStream(f);
      bmp.compress(Bitmap.CompressFormat.PNG, 80, out);
      out.flush();
      out.close();
      Uri uri = FileProvider.getUriForFile(NativePhoto.this.getApplicationContext(),
          "com.lipuwulian.blesample.provider", f);//这个是版本大于Android7.0（包含）临时访问文件，没有这个会报异常
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace(); }

    ArrayList<Uri> imageUris = new ArrayList<Uri>();
    imageUris.add(UrigetImageContentUri(NativePhoto.this,new File(photoPath)));//这个是分享本地存储的图片
    imageUris.add(UrigetImageContentUri(NativePhoto.this,f));
    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
    if(shareTag==0){
      shareIntent.setComponent(comp1);//分享给微信朋友圈
    }else if(shareTag==1){
      shareIntent.setComponent(comp);//分享给微信朋友
    }
    //如果去掉shareIntent.setComponent("*");系统会调出所有的分享软件
    shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
    shareIntent.setType("image/*");
    startActivity(shareIntent);

  }
