我做托盘搜索，但我没有得到任何帮助！
答案 0 :(得分：1)
首先，使用确切版本的Google Play服务，并仅指定您的应用使用的特定Google Play服务API。例如，如果您正在使用位置，则只需要以下依赖项：
implementation 'com.google.android.gms:play-services-location:15.0.1'
第二次，使用与compileSdkVersion版本相同的Android支持库版本。您正在使用以下内容：
implementation files('libs/support-v4-19.0.1.jar')
您需要将其更改为以下内容：
implementation 'com.android.support:support-v4:27.1.1'
support-v4-19.0.1.jar文件。
最后，您的依赖关系应该是这样的：
dependencies {
implementation 'com.google.android.gms:play-services-location:15.0.1'
implementation files('libs/dagger-1.2.2.jar')
implementation files('libs/javax.inject-1.jar')
implementation files('libs/nineoldandroids-2.4.0.jar')
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:multidex:1.0.1'
}
答案 1 :(得分：1)
我通过替换implementation ('com.android.support:support-v4:27.1.1')
而不是implementation files('libs/support-v4-19.0.1.jar')
答案 2 :(得分：1)
请勿忽略梯度依赖性版本错误警告/错误，
使用新的依赖项（如果可以），或者编写解决策略以强制使用应用程序依赖项所使用的旧库的更新版本。
在我的情况下，有conflict和ActionBarDrawableToggle版本为 23. 。。我所使用的依赖项。 我被迫在整个应用程序中起诉27.1.1版的support-v4 ，而忽略了依赖项中嵌入的版本。
configurations.all {
resolutionStrategy {
force "com.android.support:support-v4:27.1.1"
}
}

使用aar而不是jar。试试这一行

并删除此行
implementation "com.android.support:support-v4:19.0.1"
答案 4 :(得分：0)
有时由于一些不必要的或未使用的第三方库而出现此问题。
例如，我使用时出现错误
implementation 'com.kbeanie:image-chooser-library:1.6.0'
我不得不从依赖中删除它，并且我的代码构建成功。
