App runs perfectly on device which I previously build, but when I extract the installed app(debug keys) it doesn't install on other device or same device (package currept). 应用程序在我之前构建的设备上运行完美，但是当我提取已安装的应用程序（调试密钥）时，它不会安装在其他设备或同一设备上（软件包当前）。

2 个解决方案

You need to disable Instant Run first, because debug apk built with Instant Run will not run on phone with different api level from your test device. 您需要先禁用“ 即时运行” ，因为使用“即时运行”构建的调试apk无法在测试设备上具有不同api级别的手机上运行。

Then you need to clean up and build the apk. 然后你需要清理并构建apk。 If building apk seems like forever, make sure your internet connection is up. 如果构建apk似乎永远，请确保您的互联网连接已启动。

To Fix this Issue no need to enable gradle online mode. 要解决此问题，无需启用gradle在线模式。 I just cleaned Project and done rebuild. 我刚刚清理了Project并完成了重建。 Then restarted Android studio. 然后重启Android工作室。 Now it's build apk very fast. 现在它构建apk非常快。 It's recommend to enable gradle offline mode (not for initial build and when importing new libs) 建议启用gradle offline模式（不适用于初始构建和导入新库时）
