新建安卓项目中的各种问题

1setting.gradle

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
    }
}

编译报错：

 

 

What went wrong:
Execution failed for task ':app:mergeDebugNativeLibs'.
> Could not resolve all dependencies for configuration ':app:debugRuntimeClasspath'.
   > Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven(http://maven.aliyun.com/nexus/content/groups/public/)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.3.3/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details. 

如何修改：

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}

3 安卓代码如何触发nativeactivity的回调：

extern "C" JNIEXPORT void ANativeActivity_onCreate(ANativeActivity *activity,
                                                   void *savedState,
                                                   size_t savedStateSize) {

  activity->callbacks->onStart = onStart;
  activity->callbacks->onResume = onResume;
  activity->callbacks->onSaveInstanceState = onSaveInstanceState;
  activity->callbacks->onPause = onPause;
  activity->callbacks->onStop = onStop;
  activity->callbacks->onDestroy = onDestroy;
  activity->callbacks->onWindowFocusChanged = onWindowFocusChanged;
  activity->callbacks->onNativeWindowCreated = onNativeWindowCreated;
  activity->callbacks->onNativeWindowResized = onNativeWindowResized;
  activity->callbacks->onNativeWindowRedrawNeeded = onNativeWindowRedrawNeeded;
  activity->callbacks->onNativeWindowDestroyed = onNativeWindowDestroyed;
  activity->callbacks->onInputQueueCreated = onInputQueueCreated;
  activity->callbacks->onInputQueueDestroyed = onInputQueueDestroyed;
  activity->callbacks->onContentRectChanged = onContentRectChanged;
  activity->callbacks->onConfigurationChanged = onConfigurationChanged;
  activity->callbacks->onLowMemory = onLowMemory;


}

 

3.1注意activity的继承关系是NativeActivity

public class MainActivity extends NativeActivity 
继承 NativeActivity  不是app activity

3.2 如果设置了页面跳转，由MainActivity extends AppCompatActivity跳到NativeActivity，manifest.xml(一定要加，否则会闪退)

  <meta-data
                android:name="android.app.lib_name"
                android:value="native-activity" />

-------------------------------------------------------

<activity android:name=".CCActivity" 
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
