我想使用适用于手机和平板电脑的Android设备的唯一ID.(IMEI不适用于没有SIM卡设备,有时MAC地址返回null)

我不确定android.os.Build.SERIAL是否唯一.

有谁知道这个？

感谢和问候.

我已经花了一天时间在Android项目中使用CircleCI,并且我继续得到java.lang.UnsupportedClassVersionError:com/android/build/gradle/AppPlugin:当CircleCI运行gradle dependencies命令时,不支持major.minor版本52.0.这是一个堆栈跟踪,它显示:

* Where:
Build file '/home/ubuntu/MyProject/app/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.
> java.lang.UnsupportedClassVersionError: com/android/build/gradle/AppPlugin : Unsupported major.minor version 52.0

* Try:
Run with --info or --debug option to get more log output.

我现在正在将CircleCI用于我的项目.我也在我的项目中实现新的constraintLayout.现在我被CircleCI大楼困住了.它在gradle -dependencies运行时向我显示:

File /home/ubuntu/.android/repositories.cfg could not be loaded.

我按照此处的说明实施Googlemap for business(选项2:将SDK导入为库模块):

我正在尝试将Jack-Jill和Java8用于我的Android应用程序.我的笔记本电脑上的一切都很好,但当我试图在CircleCI上运行该项目时,它仍然被卡住了 transformClassesWithPreJackPackagedLibrariesForDebug

这是我的build.gradle

apply plugin: 'io.fabric'
apply from: 'test-environment.gradle'



buildscript {

我正在开发Android平板电脑应用程序,我必须管理应用程序方向.我遇到了一个问题,每当我旋转设备onCreate()时都会被调用.

我通过在活动标记的Manifest.xml文件中设置此行来修复Honeycomb(3.1)上的这个问题,它运行良好.

          android:configChanges="keyboardHidden|orientation"

但是当我在ICS Tablet上测试我的应用程序时,这个问题又回来了.有谁知道如何解决这个问题？

谢谢

问候.
