我刚刚将gradle版本更新为

classpath 'com.android.tools.build:gradle:3.0.0-beta1'

将android studio更新为3.0-beta1之后,我的gradle-wrapper是:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip

问题是,当我想要Gradle-sync项目时,我正面临这个奇怪的问题:

我在Android上遇到了一个奇怪的问题.当我通过我的应用程序发送短信时,我想听取发送意图.这是我到目前为止所做的:

private void shootSMS(String number,long currentTime){
    SmsManager smsManager = SmsManager.getDefault();

    Intent sentIntent = new Intent(SentBroadcastReceiver.SENT_ACTION);
    Intent deliveredIntent = new Intent(DeliveredBroadcastReceiver.DELIVERED_ACTION);

    Bundle b = new Bundle();
    b.putString("num",number);
    b.putString("record_time",currentTime+"");

    sentIntent.putExtras(b);
    deliveredIntent.putExtras(b);


    PendingIntent sentPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,sentIntent,PendingIntent.FLAG_ONE_SHOT);
    PendingIntent deliveredPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,deliveredIntent,PendingIntent.FLAG_ONE_SHOT);
    smsManager.sendTextMessage(number,null,getString(R.string.app_name),sentPendingIntent,deliveredPendingIntent);

}

现在的问题是,当onReceive()调用我的广播接收器的getResultCode()方法时,我调用该方法,它总是返回-1!即使手机关闭,也无法跟踪短信是否已发送!

我用GoSMSPro检查了号码并发送了一条失败的短信.有趣的是,当我把我的手机在飞行模式下,我得到的结果代码等于2这是SmsManager.RESULT_ERROR_RADIO_OFF

现在问题是这里有什么问题？

三星手机中有一个奇怪的例外,特别是Galaxy S7 Edge,我们在Fabric崩溃报告中注意到了这一点:

这就是我项目的依赖项：

dependencies {
implementation "com.android.support:appcompat-v7:27.1.1"
implementation "com.android.support:support-v4:27.1.1"
api "com.android.support:mediarouter-v7:27.1.1"
api "com.google.android.gms:play-services-cast-framework:15.0.1"
implementation 'com.jakewharton.timber:timber:4.7.0'

}

在尝试同步我的android gradle之后，我得到：

无法解决：support-core-ui

我知道support-v4中包含了support-core-ui，但我想不出任何解决方案，如果有人对此有任何想法，我将不胜感激
