问题描述

大约10天前，我的应用程序开始记录此异常（在开发人员控制台上看到）：

about 10 days ago, my app started to record this exception (seen on dev console):

java.lang.NullPointerException:
  at org.chromium.android_webview.AwContents$AwViewMethodsImpl.onDragEvent (AwContents.java:191)
  at com.android.webview.chromium.WebViewChromium.onDragEvent (WebViewChromium.java:782)

我不知道它可能是（所以我不能复制它）并且stacktrace不覆盖我的所有类。关于这个例外，我只知道：

I've no idea it could be (so i can't replicate it) and stacktrace covers none of my classes. About this exception I only know that:

仅影响具有android 7或7.1的设备

first时间发生在2017年10月11日

它每天发生约50次，直到2017年11月5日

它从2017年11月6日到现在爆炸了大约340次每天出现的次数

effects only devices with android 7 or 7.1
first time occurred 11 Oct 2017
it occurred about 50 times per days, until 5 Nov 2017
it exploded from 6 Nov 2017 until now with about 340 occurrences per day

Users-app-use的使用稳定期约为1年（每天3000次，每天15分钟）。
App是一种单人纸牌游戏（不使用libgdx框架）。

Users-app-usage is stable from about 1 year (3000 sessions per days, 15minutes per sessions).App is a solitaire card games (no framework as libgdx used).

这是我的build.gradle：

This is my build.gradle:

apply plugin: 'com.android.application'

android {
    useLibrary 'org.apache.http.legacy'
    compileSdkVersion 25
    buildToolsVersion '25.0.3'
    defaultConfig {
        applicationId "com.pisano.app.solitari"
        minSdkVersion 15
        targetSdkVersion 23

        multiDexEnabled = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
        debug {
            signingConfig signingConfigs.config
        }
    }

    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
    compile project(':pagecontrol')
    compile 'com.facebook.android:facebook-android-sdk:4.26.0'
    compile 'com.google.android.gms:play-services-games:11.2.2'
    compile 'com.google.android.gms:play-services-plus:11.2.2'
    compile 'com.google.android.gms:play-services-analytics:11.2.2'
    compile 'com.google.android.gms:play-services-location:11.2.2'
    compile 'com.google.firebase:firebase-core:11.2.2'
    compile 'com.google.firebase:firebase-ads:11.2.2'

}

apply plugin: 'com.google.gms.google-services'

非常感谢。
