关于安卓 release 版本闪退的问题

[feilong]

之前一直编译成为 debug 版本没有问题，但是切换到 release 版本时候，安卓 4.4 闪退了安卓 8.1 正常运行，求助大佬们

apk 是这个 https://github.com/feilongfl/Cimoc/releases/download/sign10/Cimoc.apk

代码 https://github.com/feilongfl/Cimoc/tree/test-sign

release 做了混淆？ 目测混淆配置方面问题。
闪退可以看 logcat，那些详细信息基本可以定位到问题。

上网查了一推，看了 android monitor 的记录

错误是这么说的
> 03-22 19:02:03.516: W/System.err(4259): at com.hiroshi.cimoc.App.onCreate(App.java:59)

app.java：59 是
> Fresco.initialize(this);

@XinLake
按照你的说法，去掉了下面这四行

```
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
shrinkResources true
zipAlignEnabled true
```

然后竟然真的没问题了，但是问题的根本应该不是这里吧

[zjp]

大概率是混淆的问题 检查 proguard 文件

[feilong]

@zjp 感谢大佬们分析
fork 别人的项目，这是我头一次看到混淆😭，看到这个文件一脸懵逼，慢慢百度中😭

proguard-rules.pro

```
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\Developer\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface

#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;

我跑到 fresco 官网上，参考（抄上）这个( https://www.fresco-cn.org/docs/proguard.html)[https://www.fresco-cn.org/docs/proguard.html]，然后编译可以运行了(ಥ _ ಥ)

@XinLake @zjp
感谢两位大佬指出问题

[zjp]

@feilong 我遇到的所有在 debug 包正常但 release 有问题的情况都是因为混淆规则没写好😂

[Jimjay]

logcat 有日志吗

[feilong]

@Jimjay
2 楼有 android monitor 的日志，和 logcat 一不一样我就不知道了
