我需要通过Video实现修剪操作.我正在使用此代码,它在Gallery2软件包安装的手机上完美运行.但它没有返回onActivityResult(如果攻击成功,意图不会返回任何结果).

码:

Intent trimVideoIntent = new Intent("com.android.camera.action.TRIM");

            // The key for the extra has been discovered from com.android.gallery3d.app.PhotoPage.KEY_MEDIA_ITEM_PATH
            trimVideoIntent.putExtra("media-item-path", FilePath);
            trimVideoIntent.setData(videoUri);

            // Check if the device can handle the Intent
            List<ResolveInfo> list = getPackageManager().queryIntentActivities(trimVideoIntent, 0);
            if (null != list && list.size() > 0) {
                startActivityForResult(trimVideoIntent,2); // Fires TrimVideo activity into being active
            }else {
                Toast.makeText(this, "Video trimming not supported", 1).show();
            }

有没有办法在修剪和返回结果后关闭gallery2？

我启动一个具有android原生webView(android.webkit.WebView)的Activity,我在64位设备中得到以下错误.

error instantiating provider                                                                 java.lang.RuntimeException: Cannot load WebView
at org.chromium.android_webview.AwBrowserProcess.loadLibrary(AwBrowserProcess.java:52)

Caused by: org.chromium.base.library_loader.ProcessInitException

Caused by: java.lang.UnsatisfiedLinkError: dlopen failed: "/data/app/com.google.android.webview-1/lib/arm/libwebviewchromium.so" is 32-bit instead of 64-bit

请提供一些有价值的建议.

我在一个需要stackview的应用程序中.但是我必须实现水平滑动以在stackview项和UI外观之间切换为正常的.请帮我搞定.

我已经检查了这个链接.

但在它中UI只是一个封面流程.我想让UI看起来像stackview一样.

我正在尝试使用从服务器端（用 python 编码）应用程序生成的签名 URL 将视频文件从 android 应用程序上传到 S3 服务器中的存储桶。我们正在向签名的 URL 发出 PUT 请求，但我们得到了

connection reset by peer exception.

但是当我在 POSTMAN REST CLIENT 上尝试相同的 URL 时，会收到一条成功消息。任何帮助将不胜感激。

在将com.android.support:design lib更新为24.2.0之后,在android.support.design.widget.FloatingActionButton中得到了ClassCastException.它在lib版本24.1.1中正常工作
