1、處理閃屏的問題需要在valus下的styles.xml下處理

下面是路徑沒有就新建一個

主要的就是選中的那個

在AndroidManifest.xml配置一下

上面配合完成就不閃了

2、啟動太慢怎麼處理的問題

我使用的是

InitService


import android.app.IntentService;
import android.content.Context;
import android.content.Intent;
import android.os.Build;

import com.umeng.analytics.MobclickAgent;


import cn.jpush.android.api.JPushInterface;

/**
 * An {@link IntentService} subclass for handling asynchronous task requests in
 * a service on a separate handler thread.
 * <p>
 * <p>
 * app  開啟的時候 初始化 操作  減少app 開啟的效率
 * TODO: Customize class - update intent actions, extra parameters and static
 * helper methods.
 */
public class InitService extends IntentService {
    // TODO: Rename actions, choose action names that describe tasks that this
    // IntentService can perform, e.g. ACTION_FETCH_NEW_ITEMS
    private static final String ACTION_FOO = "com.xinli.vkeeper.services.action.FOO";


    /**
     * Instantiates a new Init service.
     */
    public InitService() {
        super("InitService");
    }

    /**
     * Starts this service to perform action Foo with the given parameters. If
     * the service is already performing a task this action will be queued.
     *
     * @param context the context
     * @see IntentService
     */
// TODO: Customize helper method
    public static void startActionFoo(Context context) {
        try {
            Intent intent = new Intent(context, InitService.class);
            intent.setAction(ACTION_FOO);

        /*    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                context.startForegroundService(intent);
            } else {*/
                context.startService(intent);
           // }
        } catch (Exception e) {
            e.printStackTrace();

        }

    }


    @Override
    protected void onHandleIntent(Intent intent) {
        if (intent != null) {
            final String action = intent.getAction();
            if (ACTION_FOO.equals(action)) {
                LoadInit();
            }
        }
    }


    /**
     * 初始化操作資料
     */
    private void LoadInit() {
        CrashHandler crashHandler = CrashHandler.getInstance();
        crashHandler.init(MyApplication.getAppContext());
        JPushInterface.init(MyApplication.getAppContext());
        if (JPushInterface.isPushStopped(MyApplication.getAppContext())) {
            JPushInterface.resumePush(MyApplication.getAppContext());
        }
        MobclickAgent.setCatchUncaughtExceptions(true);
        MobclickAgent.startWithConfigure(new MobclickAgent.UMAnalyticsConfig(MyApplication.getAppContext(), Config.KEY,"Umeng", MobclickAgent.EScenarioType.E_UM_ANALYTICS_OEM,true));

        MobclickAgent.enableEncrypt(true);
        MobclickAgent.setCheckDevice(true);

    }

}
<service
    android:name=".receiver.InitService"
    android:exported="false" />

在application中這樣使用就好了

InitService.startActionFoo(context);
