之前做app功能遍历的项目中使用的是monkeyrunner+hierarchyviewer的方式，但是hierarchyviewer提供的信息太多而且无用的信息居多，所以想换成
monkeyrunner+uiautomatorviewer的方式来做。但是在集合的时候调用monkeyrunner和uiautomator时出错： publicvoidtest_Exception(){ System.setProperty("com.android.uiautomator.bindir","D:/sdk/tools"); DebugBridge.init(); MyDeviceManagermanager=null; IDeviceidevice=null; try{ Thread.sleep(3000); List<IDevice>devices=DebugBridge.getDevices(); idevice=devices.get(0); manager=newMyDeviceManager(idevice); getUIHierarchy(idevice); }catch(Exceptione){ e.printStackTrace(); }finally{ manager.dispose(); DebugBridge.terminate(); } } privatevoidgetUIHierarchy(IDeviceidevice){ Stringpath=System.getProperty("user.dir")+File.separator+"xml"+File.separator+"uidump.xml"; Stringcommand=String.format("%s%s%s",newObject[]{"/system/bin/uiautomator","dump", "/data/local/tmp/qianhui.xml"}); CountDownLatchcommandCompleteLatch=newCountDownLatch(1); try{ idevice.executeShellCommand(command,newCollectingOutputReceiver(commandCompleteLatch),40000); commandCompleteLatch.await(40L,TimeUnit.SECONDS); System.out.println("PullUIXMLsnapshotfromdevice...1212"); idevice.getSyncService().pullFile("/data/local/tmp/qianhui.xml",path,SyncService.getNullProgressMonitor()); }catch(Exceptione){ //TODOAuto-generatedcatchblock e.printStackTrace(); } } |
在MyDeviceManager构造方法中执行的是创建monkey对象：
publicMyDeviceManager(IDeviceiDevice){
this.mIDevice=iDevice;
this.mAdbChimpDevice=newAdbChimpDevice(iDevice);
/*Stringwidth=mAdbChimpDevice.getProperty("display.width");
System.out.println(width);
Stringheight=mAdbChimpDevice.getProperty("display.height");
System.out.println(height);
sWidth=Integer.parseInt(width);
sHeight=Integer.parseInt(height);*/
}
当我执行上面的代码时报错：

而当我把
manager=newMyDeviceManager(idevice);
getUIHierarchy(idevice);
的位置调换一下，执行成功。所以我怀疑monkeyrunner在启动的时候已经创建了uiautomator的对象，才会造成上面的提示错误，所以我试图去查看一下monkeyrunner到底有没有做这件事。
查看AdbChimpDevice创建的源码，发现
Stringcommand=newStringBuilder().append("monkey--port").append(port).toString();
executeAsyncCommand(command,newLoggingOutputReceiver(LOG,Level.FINE));
这一步是打开monkey，在cmd下执行该命令就能知道：
