어느날 APK를 생성하니
아래와 같이 에러가 발생 되었습니다.
자세히 확인해 보니 jcenter()에서 api를 가져오지 못하는것으로 보입니다.
그래서
build.gradle의 jcenter() 호출하는 부분을 mavenCentral()로 변경 했더니 해결이 되었습니다.
As-Is
To-Be
위의 To-Be 와 같이 하였을 때도 동일하게 오류가 발생 될경우
jcenter() 호출하는 부분을 하나하나 mavenCentral()로 바꿔 보면 해결되는지 확인하면 될듯 합니다.
아래와 같이 에러가 발생될 경우
Caused by: com.android.builder.errors.EvalIssueException: Configuration `:app:debugRuntimeClasspath` contains AndroidX dependencies, but the `android.useAndroidX` property is not enabled, which may cause runtime issues.

특정 URL로 통신하니
java.io.IOException: Cleartext HTTP traffic to test.tlshenm.com not permitted 오류가 발생되었습니다.
안드로이드 파이(9)부터 Http 통신시 발생된다고 하더군요...
해결방법
Https 통신으로 바꾸거나 바꿀수 없으면 허용을 해줘야 합니다.
저는 허용하는 방법을 안내하겠습니다.
1. res/xml폴더를 생성하시구요
2. res/xml/network_security_config.xml파일을 생성합니다.
3. 아래그림과 같이 예외처리할 URL(test.tlshenm.com)을 넣어 줍니다.
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">localhost</domain>
<domain includeSubdomains="true">test.tlshenm.com</domain>
</domain-config>
</network-security-config>
마지막으로 AndroidManifast.xml안에 <application> 태그안에 아래 코드를 넣어 줍니다.
<application
android:networkSecurityConfig="@xml/network_security_config"
. . . . . .>
이제 빌드해보시면 정상적으로 동작되실겁니다.
오랜만에 새로운 버전으로 빌드해보니 오류가 발생되었습니다.
Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.
31 SDK를 설치해도 동일하게 발생되더군요.
해결방법
SDK를 30으로 낮춘다...
(나중에 31로 플레이스토어에 배포하라 그러면 어쩌라는 거냐...)
그럼 빌드 되실겁니다.
아래와 같이 에러가 발생하였을때
ERROR: Unable to find method 'org.gradle.api.tasks.compile.CompileOptions.setBootClasspath(Ljava/lang/String;)V'.
Possible causes for this unexpected error include:
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
Project/gradle/wrapper/gradle-wrapper.properties 파일로 들어가서
5.1.1부분을 4.6이라던지 4.1로 버전을 변경해보시면 정상 빌드 되실겁니다.
그래도 안되시면
안드로이드 스튜디오를 종료후 재시작 해보시거나
File/Sync Project with Gradle File를 눌러 보시기 발랍니다.

이번에 알림기능을 넣고 앱을 테스트 하면서
안드로이드 ics 버전에서 앱이 죽는 현상이 발생하여 다음과 같이 해결
public static void ViewNotice(String notiTitle ,String notiContent,Context context){ NotificationManager mNM; mNM = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); Intent mI = new Intent(); mI.setClass(context, NotiViewActivity.class); mI.putExtra("NOTICE", notiContent); mI.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, mI, PendingIntent.FLAG_UPDATE_CURRENT); Notification notification = null; //안드로이드 버전 체크 if(Build.VERSION_CODES.KITKAT<Build.VERSION.SDK_INT){ //킷켓보다 버전 보다 높을 경우
Notification.Builder builder = new Notification.Builder(context); builder.setSmallIcon(R.drawable.icon_t); builder.setWhen(System.currentTimeMillis()); builder.setContentTitle("공지 제목"); builder.setContentText("공지 내용"); builder.setContentIntent(contentIntent); notification = builder.build(); }else{ //킷켓 버전이하일 경우
notification = new Notification(R.drawable.icon_t, null, System.currentTimeMillis()); notification.setLatestEventInfo(context, "공지 제목","공지 내용", contentIntent); } notification.flags |= Notification.FLAG_AUTO_CANCEL; notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE; notification.defaults |= Notification.DEFAULT_SOUND; mNM.notify(0, notification); }
특정버전 이하에서는 Notification notification = builder.build(); 지원하지 않는것 같음
안드로이드 ics 버전에서는 다음과 같이 정의하면 오류가 나지 않는다.
notification = new Notification(R.drawable.icon_t, null, System.currentTimeMillis()); notification.setLatestEventInfo(context, "공지 제목","공지 내용", contentIntent);
간혹 안드로이드 스튜디오를 실행해보면 다음과 같은 오류를 만날 수 있습니다.
Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html
Please read the following process output to find out more:
-----------------------
Error occurred during initialization of VM

이럴 경우 당황하지 말고
gradle.properties 파일로 들어가서 Xmx1536m -> Xmx512m 으로 변경해준다.
저장 후 상단 오른쪽에 Try again을 눌러주면 끝
