Fixing "DerInputStream.getLength(): lengthTag=109, too big" in Android Studio
This happened to me in Android Studio after AndroidX migration and using the new testing framework. Even deleting the existing ~/.android/debug.keystore was failing for me The solution was regenerate it manually (accept all questions as empty and say yes at the last one) $ keytool -genkey -v -keystore debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000 And copy it $ rm ~/.android/debug.keystore $ cp debug.keystore ~/.android/debug.keystore
