Android的启动从另一个应用程序没有上传文件中的谷歌应用程序驱动器

问题描述

我试图通过手工启动谷歌驱动器（安装在设备上）上载从我的Andr​​oid应用程序的文件。我试图用这个 Intent.createChooser 及其工作正常上传文件附件来发送。但我需要上传特定意图的文件（如Dropbox的，谷歌只驱动器）。所以我改变了code，并试图文件到谷歌驱动器上传为以下几个方面，但没有成功，只有谷歌驱动程序是在设备上打开的，没有文件上传：

I tried to upload a file from my android application by manually launching Google drive (installed on the device). I tried this to send using Intent.createChooser and its working fine for uploading file attachment. But I need to upload file for specific intent (like Dropbox, Google drive only). So I changed the code and tried to upload a file to Google drive as following ways, but no success, only Google drive app is open on device, no file uploaded:

PackageManager pm = this.getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.google.android.apps.docs");
intent.setType("application/pdf");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://sdcard/sdcard0/test.pdf"));
intent.putExtra(Intent.EXTRA_SUBJECT, "attach a file test");
intent.addCategory(Intent.ACTION_ATTACH_DATA);
startActivity(intent);

我们可以通过手动打开的意图如上上传PDF文件？

Can we upload a PDF file by opening the intent manually as above?

推荐答案

我的研究后，执行以下code解决方案：

I got the solution for executing following code after research:

import android.support.v4.app.ShareCompat;

Uri pdfUri = Uri.parse("file://sdcard/sdcard0/test.pdf");
Intent shareIntent = ShareCompat.IntentBuilder.from(this)
                                     .setText("Share PDF doc")
                                         .setType("application/pdf")
                                         .setStream(pdfUri )
                                         .getIntent()
                                 .setPackage("com.google.android.apps.docs");
startActivity(shareIntent);

同样，我们可以使用其他的份额意图和几个意向的相应的包名称是如下：

Similarly we can use for other share intent and the corresponding package name of few intents are as below:

• com.dropbox.android = Dropbox的


• com.android.bluetooth =蓝牙


• com.android.email =电子邮件


• com.google.android.gm =的Gmail


• com.microsoft.skydrive = SkyDrive中


• com.google.android.apps.docs = Google云端硬盘

有关Gmail的共享，我们需要使用以下类型code的：

For gmail sharing we need to use following type of code:

Uri zipUri = Uri.parse("file://sdcard/sdcard0/test.zip");
String[] emailArr = {"[email protected]"};
Intent shareIntent = ShareCompat.IntentBuilder.from(this)
                                  .setText("Share ZIP doc")
                                  .setType("application/zip")
                                  .setEmailTo(emailArr)
                                  .setStream(zipUri)
                                  .setSubject("Share zip doc")
                                  .setText("Sent with email app.")
                                  .getIntent()
                           .setPackage("com.google.android.gm");
startActivity(shareIntent);
