Stop buffering of adb shell output

I observed this new behavior in adb v1.0.39. The command: adb shell getevent -l gives the output below: Observe that the last line is incomplete. This happens on many different devices. The same command is working without buffering in adb v1.0.32. How do I stop adb shell output buffering in adb v1.0.39?

android emulator renaming from emulator-5554 to a unique string

So when on starting up an emulator , adb devices give me emulator-5554 device All dandy till here. What i am envisioning is to create an emulator farm with multiple emulators spawned up on multiple devices. In order to uniquely differentiate from an emulator-5554 running on machine A from emulator-5554 running on machine B ,I would like to rename emulator-5554(s) to something like machineA-emulator-5554 and machineB-emulator-5554. Searching around did not find me much help ( as a majority of the questions were regarding actual device renaming). Any pointers on the above? NP:I had tried to do a

通过ADB Shell和代码了解命令-Android(Understanding command through adb shell and through code - Android)

问题 我正在尝试将BATTERSTATS权限授予某个应用。 当我从PC上运行命令时-可以正常工作: adb shell pm grant com.example.sample.myapplication android.permission.BATTERY_STATS 但是从Android应用程序运行pm grant ,相同的pm grant命令不起作用: java.lang.Process process = Runtime.getRuntime().exec("pm grant com.example.sample.myapplication android.permission.BATTERY_STATS"); 要授予此权限是否需要root权限? 如果是这样,为什么不要求将设备植根以通过adb shell运行它呢? 我是Android新手,请更清楚地解释一下内部正在发生什么以及如何进行。 回答1 使用adb shell运行的命令将以shell(UID=2000)用户权限执行。 您通过java代码运行的命令将使用您应用的UID特权执行。 因此有所不同。 来源:https://stackoverflow.com/questions/38824114/understanding-command-through-adb-shell-and-through-code-android

Understanding command through adb shell and through code - Android

I am trying to give BATTERSTATS permission to an app. When I run the command from a PC - it works just fine: adb shell pm grant com.example.sample.myapplication android.permission.BATTERY_STATS But the same pm grant command does not work when run from Android app: java.lang.Process process = Runtime.getRuntime().exec("pm grant com.example.sample.myapplication android.permission.BATTERY_STATS"); Does it require root permission to give this permission? If it is so, why it does not require the device to be rooted to run it via adb shell? I am new to Android, please explain a bit more clearly what
