问题 I have MainActivite. And I try to set text to TextView tvUserName. Until today everything was Ok, but now I can't access to this variable by findViewById. Value of this variable is null.

问题 As it is known, the minimum API level for using the Android support library is 14 now. I would like to release a new version of my app (currently minSdk 15 and targetSdk 27) to support API < 14 (down to Froyo at the minimum if possible). Why you ask? I do not plan to keep supporting for these old system versions, but rather just to fix one critical bug to help the numerous users I have on these platforms - a bug which will actually help them export their data to newer versions.

问题 Why does Gradle give this error about dependencies when I have used the latest and same version? This has only just started today and I'm lost as to how to fix this: All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes).
