# Troubleshooting

Here is a summary FAQs that may be encountered during your integrating process.

1、Attempt to invoke virtual method 'void d.a.o.b.a.a(java.lang.String, java.lang.String, java.lang.String, java.lang.String)' on a null object reference.

To avoid this problem, you need to add the following configuration in your ProGuard rules to exclude AIHelp:

-keep class net.aihelp.** {*;}

2、Too many field references: xxxxx; max is 65536.

There is a limit to the total number of references in the DEX bytecode file of Android build architecture. Please refer to the official document for solutions:


3、Default interface methods are only supported starting with Android N (--min-api 24)

To fix this problem, you need to add the following code in the android { ... } of your build.gradle :

android {
  compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
