흠.. 예전에 만들었던 앱에 무슨 에러가 그렇게 난다길래 보니까 OutOfMemory 에러가 발생했다.

아마 Custom pad를 만들어 사진 캡처하는 기능을 구현했었는데 이미지 처리하던 중 메모리 부족이 발생한 듯.

 

 

1.gradle.properties

#org.gradle.jvmargs=-Xmx2048m
org.gradle.jvmargs=-Xmx4096m

일단 jvm메모리를 2배로 늘려주었다.

 

2. AndroidManifest.xml

android:largeHeap="true"

안드로이드 설정도 바꿔줬다.

 

3.gradle clean

./gradlew clean && ./gradlew : assembleDebug --no-build-cache
