I am pretty new to Android. When I build my current project I got this error:
Error:Error converting bytecode to dex: Cause:
com.android.dex.DexException: Multiple dex files define
Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionI
This is my dependencies:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.+'
compile 'com.android.support:recyclerview-v7:23.+'
compile 'com.android.support:support-v4:23.+'

compile files('libs/JTransforms-3.1-with-dependencies.jar')
compile 'com.github.Semantive:waveform-android:v1.2'
compile files('libs/TarsosDSP-Android-latest.jar')
I'm using gradle 2.13 and gradle-build 2.1.
There were someone tell me to clean the project but it didn't work. Please help.
Well if i understand you question i hope this answer can help you.
You can increase the memory size that the dexer process is allowed to use.
Open the ini file that is located in:
C:\Users\\AppData\Roaming\Anywhere Software\Basic4android
Change this line:.
MaxRamForDex=1024 To:.
MaxRamForDex=1536

第一次用as,请问这个怎么解决?

清理项目，紫薯布丁。
看看导入的jar是否有相同的
