我已将 Android Studio 更新到新的 Canary 版本，并更新了我的 gradle 文件。当我通过 run 启动我的应用程序时，出现以下错误:

Process: io.github.siddharthvenu.saltanalysis, PID: 23244

编辑:我发现上面的错误是由于Android的AdView引起的。不知何故，在我的应用中加入广告会导致它崩溃。

我想这可能是因为我没有签署 apk，所以我签署了它 (debug)，然后尝试使用 adb install 命令安装它。我得到以下输出:

Failed to install alpha_test_006.apk: Failure [INSTALL_FAILED_TEST_ONLY: installPackageLI]

最佳答案

我找到了第一种情况产生SecurityException的原因。这是因为在我的代码中包含了一个 AdView。我试图将其注释掉，但它奏效了。我怀疑这是因为只有包含 AdView 的 Activity 崩溃了。

adb install 问题仍然存在
