看起来您需要指定android.jar的路径，该路径通常位于sdk/platforms/android-version下

javah -jni -classpath /path/to/sdk/platforms/android-version/android.jar:bin/classes/ -d jni/ com.ziqitza.helper.HelloJni

或

javah -jni -bootclasspath /path/to/sdk/platforms/android-version/android.jar  -classpath bin/classes/ -d jni/ com.ziqitza.helper.HelloJni

错误：无法访问android.app.Activity
