Selendroid 不会启动某些应用程序
Selendroid won't start some apps
我得到了在设备上启动应用程序的平均设置，有时它工作得很好（应用程序启动并可以由 selendroid 控制）有时（在 firefox.apk 的情况下）会发生这种情况：

应用程序无法启动，selendroid 一直在尝试但没有任何反应。我可以毫无问题地手动启动该应用程序。
我不明白其中的区别或如何缩小问题范围。
顺便说一句：如果有人想自己尝试，我使用了 Google Play 商店中的 firefox.apk。
好的，我终于做到了：
问题是这个特定的应用程序有一个使用标签 "activity-alias" 的 AndroidManifest.xml 文件（使用例如 https://code.google.com/p/xml-apk-parser/ 读取它）。在这个标签内有 Selendroid 需要确定所谓的 "main_activity":
的字段
<activity-alias android:label="Firefox" android:name=".App" android:targetActivity="org.mozilla.gecko.BrowserApp">
<intent-filter android:priority="999">
<action android:name="android.intent.action.MAIN">
</action>
<category android:name="android.intent.category.LAUNCHER">
</category>
<category android:name="android.intent.category.MULTIWINDOW_LAUNCHER">
</category>
<category android:name="android.intent.category.DEFAULT">
</category>
</intent-filter>
不幸的是，Selendroid 不理解这个标签，因此找不到 "main_activity"。
解决方案：我不得不使用"SelendroidCapabilities.setLaunchActivity"-方法来明确告诉Selendroidactivity使用什么：
SelendroidCapabilities caps = new SelendroidCapabilities("org.mozilla.firefox:39.0");
caps.setLaunchActivity("org.mozilla.gecko.BrowserApp");
