目标:Pusher在android 5.0及以上版本工作，但4.0及以下版本无法连接pusher server。
我正在使用下面的代码
if(Utils.isOnline(mcontext)) {
try {
PusherOptions pOptions = new PusherOptions();
pOptions.setAuthorizer(new HttpAuthorizer(Constants.PUSHER_AUTH_SRC_URL + "/auth.php"));
pusher = new Pusher(Constants.PUSHER_KEY, pOptions);
/* pusher.connect(new ConnectionEventListener() {
@Override
public void onConnectionStateChange(ConnectionStateChange connectionStateChange) {
}
@Override
public void onError(String s, String s1, Exception e) {
}
}, ConnectionState.ALL);*/
pusher.connect();
//com.pusher.client.util.Factory factory;
channel = pusher.subscribe(Utils.getPref(mcontext,"channel_name", ""));
Utils.setPref(mcontext, "OtherUserId", "");
}catch(Exception e){
e.printStackTrace();
}
}
下面使用Gradle库Commen库已经试过了
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile 'com.android.support:design:23.2.1'
compile 'com.android.support:support-v4:23.2.1'

compile files('libs/afilechooser.jar')
//compile 'com.android.support:multidex:1.0.1'

最佳答案
您的 pusher 依赖与 google-play-service 依赖冲突只需从 gradle 中删除 compile 'com.google.android.gms:play-services:8.4.0' 依赖，您的问题将是解决了
关于android - Pusher 不能在 android 4.4.4 版本上工作？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41406443/
