+### Troubleshooting
+##### Out of memory error:
+  - Reduce processing threads count (`-j` option) 
+  - Increase maximum java heap size:
+    * command line (example for linux): 
+      `JAVA_OPTS="-Xmx4G" jadx -j 1 some.apk`
+    * edit 'jadx' script (jadx.bat on Windows) and setup bigger heap size:
+      `DEFAULT_JVM_OPTS="-Xmx2500M"`
