AdMob 使我的应用在发布版本中崩溃答案

【问题标题】：AdMob making my app crash in release versionAdMob 使我的应用在发布版本中崩溃
【发布时间】：2015-05-01 17:45:57
【问题描述】：

我刚刚将 AdMob 添加到我的应用中。当我调试或安装应用程序的发布版本（HTC m7）时，一切似乎都运行良好。问题出现在 CHUWI VX2 设备（esky82_tb_cn_kk，Android 4.4）上。这很奇怪，因为在这个设备上我的应用程序在调试模式下工作，但在发布版本中不工作。我尝试转向亲葫芦，但它对我没有帮助。

有人对此有想法吗？

我的清单

我的 onCreate 方法中的说明：

mAdView = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                super.onAdClosed();
                mAdView.setVisibility(View.GONE);
            }

            @Override
            public void onAdOpened() {
                super.onAdOpened();
                mAdView.startAnimation(fade_in);
                mAdView.setVisibility(View.VISIBLE);
            }

            @Override
            public void onAdFailedToLoad(int errorCode) {
                super.onAdFailedToLoad(errorCode);
                mAdView.setVisibility(View.GONE);
            }

            @Override
            public void onAdLoaded() {
                super.onAdLoaded();
                mAdView.startAnimation(fade_in);
                mAdView.setVisibility(View.VISIBLE);
            }

            @Override
            public void onAdLeftApplication() {
                super.onAdLeftApplication();
                mAdView.setVisibility(View.GONE);
            }
        });
        mAdView.loadAd(adRequest);

layout.xml 中的代码

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >        

<com.google.android.gms.ads.AdView  android:id="@+id/adView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            ads:adSize="SMART_BANNER"
            ads:adUnitId="@string/banner_ad_unit_id"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:visibility="gone">
        </com.google.android.gms.ads.AdView>
    </RelativeLayout>

Logcat 指出这一行（Main.java:450）

mAdView.setAdListener(new AdListener() {

【问题讨论】：

你能突出显示第 450 行吗？
是的。这是第 450 行： mAdView.setAdListener(new AdListener() {

标签： android admob

【解决方案1】：

这是什么？

android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"

你期待什么？打双方？

试试这个

 android:layout_alignParentRight="true"
 android:layout_alignParentEnd="true"

剩下的就放手

【讨论】：

【解决方案2】：

您在Main 的第 450 行收到 NullPointerException。看那条线。那里的东西还没有被初始化。

【讨论】：

【解决方案3】：

我解决了我的问题。此问题与 AdView 无关。这是项目的问题。我犯了一些小错误。我没有这条线

<?xml version="1.0" encoding="utf-8"?>

在 xml 布局文件的开头。我不知道它是如何工作的。

我重新启动设备
我在 xml 中添加了缺失的行
我清理项目（构建 > 清理项目）
我重建项目（构建 > 重建项目）

然后我的 apk 在没有 progourd 的情况下开始工作，但是当我启用此功能时崩溃。所以我找到this solution

我配置progourd配置文件like this。
