开发一个优秀的Android应用你必须要加入的代码及配置

1 . 开发一个Android App我们一般需要继承Application来初始化一些配置,如下所示：
a. Application中有一个registerActivityLifecycleCallbacks()方法，可以在回调中把整个应用打开的Activity保存在集合中、销毁的Activity重集合中删除。个人觉得这种方式比BaseActivity的方式或者每打开一个Activity把当前的引用加入到集合中的方式优雅多了，推荐大家用这种方式。关闭应用也非常方便，遍历保存Activity的集合，�执行finish()就好。
/**
* 注册ActivityListener
*/
private void registerActivityListener() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
@Override
public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
if (null == mActivitys) {
return;
}
mActivitys.add(activity);
}
@Override
public void onActivityStarted(Activity activity) {}
@Override
public void onActivityResumed(Activity activity) {}
@Override
public void onActivityPaused(Activity activity) {}
@Override
public void onActivityStopped(Activity activity) {}
@Override
public void onActivitySaveInstanceState(Activity activity, Bundle outState) {}
@Override
public void onActivityDestroyed(Activity activity) {
if (null == activity && mActivitys.isEmpty()) {
return;
}
if (mActivitys.contains(activity)) {
mActivitys.remove(activity);
}
}
});
}
}
b. 严苛模式StrictMode：建议大家在Debug版本打开严苛模式。 例如：严苛模式下可以检测到你应用中没有关闭的流，可以减少OOM，如下所示，可以看到在在控制台严苛模式模式下的Log输出。

ThreadPolicy线程策略检测
自定义的耗时调用 使用detectCustomSlowCalls()开启
磁盘读取操作 使用detectDiskReads()开启
磁盘写入操作 使用detectDiskWrites()开启
网络操作 使用detectNetwork()开启
VmPolicy虚拟机策略检测
Activity泄露 使用detectActivityLeaks()开启
未关闭的Closable对象泄露 使用detectLeakedClosableObjects()开启
泄露的Sqlite对象 使用detectLeakedSqlLiteObjects()开启
检测实例数量 使用setClassInstanceLimit()开启
/**严苛模式主要检测两大问题，一个是线程策略，即TreadPolicy，另一个是VM策略，即VmPolicy。*/
if (AppConfig.IS_DEBUG && Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectAll().penaltyLog().build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectAll().penaltyLog().build());
}
c .在onCreate中，检测当前进程名称是否为应用包名，否则return （像百度地图等sdk需要在单独的进程中执行，会多次执行Application的onCreate()方法，所以为了只初始化一次应用配置，作此判断），代码如下：
/**检测当前进程名称是否为应用包名，否则return （像百度地图等sdk需要在单独的进程中执行，会多次执行Application的onCreate()方法，所以为了只初始化一次应用配置，作此判断）*/
if (!CommonUtil.getCurProcessName(this).equals(getPackageName())) {
return;
}
d . �Crash全局异常捕获，用到了一个第三方库,使用方法如下：
compile 'cat.ereza:customactivityoncrash:1.5.0'
CustomActivityOnCrash.install(this);
应用发生异常时customactivityoncrash库�会打开一个如下图所示的Activity页面，可以查看错误。

e .其他配置初始化
private void init() {
/**注册ActivityListener*/
registerActivityListener();
/**crash异常捕获*/
if (AppConfig.IS_DEBUG) {
CustomActivityOnCrash.install(this);
}
/**初始化base url*/
if (AppConfig.IS_DEBUG) {
final String base_url = SPUtils.getString(SPUtils.DEFAULT_FILE_NAME, SharePrefsConstant.SP_BASE_URL, "");
if (TextUtils.isEmpty(base_url)) return;
AppConfig.updateAllUrl(base_url);
}
/**初始化LeakCanary */
if (AppConfig.IS_DEBUG) {
if (LeakCanary.isInAnalyzerProcess(this)) {
return;
}
LeakCanary.install(this);
}
}
2 .�完整MyApplication代码，如下所示：
public class MyApplication extends Application {
private static MyApplication application;
/**
* 维护Activity的List
*/
private static List<Activity> mActivitys = Collections.synchronizedList(new LinkedList<Activity>());
@Override
public void onCreate() {
/**严苛模式主要检测两大问题，一个是线程策略，即TreadPolicy，另一个是VM策略，即VmPolicy。*/
if (AppConfig.IS_DEBUG && Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectAll().penaltyLog().build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectAll().penaltyLog().build());
}
super.onCreate();
application = this;
/**检测当前进程名称是否为应用包名，否则return （像百度地图等sdk需要在单独的进程中执行，会多次执行Application的onCreate()方法，所以为了只初始化一次应用配置，作此判断）*/
if (!CommonUtil.getCurProcessName(this).equals(getPackageName())) {
return;
}
/**初始化一些应用配置*/
init();
}
private void init() {
/**注册ActivityListener*/
registerActivityListener();
/**crash异常捕获*/
if (AppConfig.IS_DEBUG) {
CustomActivityOnCrash.install(this);
}
/**初始化base url*/
if (AppConfig.IS_DEBUG) {
final String base_url = SPUtils.getString(SPUtils.DEFAULT_FILE_NAME, SharePrefsConstant.SP_BASE_URL, "");
if (TextUtils.isEmpty(base_url)) return;
AppConfig.updateAllUrl(base_url);
}
/**初始化LeakCanary */
if (AppConfig.IS_DEBUG) {
if (LeakCanary.isInAnalyzerProcess(this)) {
return;
}
LeakCanary.install(this);
}
}
public static MyApplication getApplication() {
return application;
}
public static void finishAllActivity() {
if (mActivitys == null || mActivitys.isEmpty()) {
return;
}
for (Activity activity : mActivitys) {
activity.finish();
}
}
/**
* 获取当前Activity（栈中最后一个压入得）
*/
public static Activity getCurrentActivity() {
if (mActivitys == null || mActivitys.isEmpty()) {
return null;
}
Activity activity = mActivitys.get(mActivitys.size() - 1);
return activity;
}
/**
* 注册ActivityListener
*/
private void registerActivityListener() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
@Override
public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
if (null == mActivitys) {
return;
}
mActivitys.add(activity);
}
@Override
public void onActivityStarted(Activity activity) {}
@Override
public void onActivityResumed(Activity activity) {}
@Override
public void onActivityPaused(Activity activity) {}
@Override
public void onActivityStopped(Activity activity) {}
@Override
public void onActivitySaveInstanceState(Activity activity, Bundle outState) {}
@Override
public void onActivityDestroyed(Activity activity) {
if (null == activity && mActivitys.isEmpty()) {
return;
}
if (mActivitys.contains(activity)) {
mActivitys.remove(activity);
}
}
});
}
}
}
3 . 应用的入口SplashActivity的onCreate方法中要加入如下代码，解决首次安装应用，点击应用图标打开应用，点击home健回到桌面，再次点击应用图标，进入应用时多次初始化SplashActivity的问题
/**在应用的入口activity加入以下代码，解决首次安装应用，点击应用图标打开应用，点击home健回到桌面，再次点击应用图标，进入应用时多次初始化SplashActivity的问题*/
if ((getIntent().getFlags() & Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) != 0) {
finish();
return;
}
if (!isTaskRoot()) {
finish();
return;
}
4 . �app下的build.gradle配置，代码如下
apply plugin: 'com.android.application'
apply plugin: 'com.antfortune.freeline'
android {
//国内镜像地址来下载 $ ./gradlew initFreeline -Pmirror
freeline {
hack true

if (outputFile != null && outputFile.name.endsWith('.apk')) {

}
5 . 应用根目录下得build.gradle文件配置，代码如下：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
ext {
compileSdkVersion = 25
buildToolsVersion = "25.0.3"
minSdkVersion = 15
targetSdkVersion = 22
versionCode = 1
versionName = "1.0.0"
espressoCore = "2.2.2"
junit = "4.12"
constraintLayout = "1.0.2"
customactivityoncrash = "1.5.0"
leakcanaryVersion = "1.5.1"
appcompatV7 = "25.3.1"
design = "25.3.1"
supportVectorDrawable = "25.3.1"
}
buildscript {
repositories {
jcenter()
mavenCentral()
maven { url 'https://jitpack.io' }
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'
classpath 'com.antfortune.freeline:gradle:0.8.7'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
6 . 应用的混淆配置文件，代码如下：
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
public *;
}
#webView js调用不混淆，否则取不到数据
-keepclassmembers class com.zyp.ui.WebActivity$* {

}
#shrink，测试后发现会将一些无效代码给移除，即没有被显示调用的代码，该选项 表示 不启用 shrink。
#-dontshrink

-keep public class com.zyp.R$*{

7 . 此Demo的功能，可以在应用内切换Base_Url,退出登录时还原默认的Base_Url ,导出应用的私有数据到SD卡上，个人觉得这几个功能，是我们开发app时很需要的功能，如下所示：
image.png
8 . 混淆前后文件目录变化如下图所示，其中mapping.txt文件为混淆的映射文件，每个版本要注意保存起来（Umeng上需要导入这个文件的）。
image.png
9 . 对系统Log类的封装Logger类，可以在控制台打印出如下图所示的功能，主要实现代码如下：
StackTraceElement stackTrace = Thread.currentThread().getStackTrace()[4];
StringBuilder sb = new StringBuilder();
sb.append("(")
.append(stackTrace.getFileName())
.append(":")
.append(stackTrace.getLineNumber())
.append(")")
.append("#")
.append(stackTrace.getMethodName())
.append(":")
.append(CommonUtil.unicode2GBK(sb1.toString()));//服务器返回的汉字可能是unicode编码，所以在此转成GBK
image.png
10 . 最后还有一个小Tips要送大家，大家其实发现了我应用中使用的全是AppConfig.IS_DEBUG而不是BuildConfig.DEBUG,这是为什么呢？主要是为了避免导错BuildConfig的包名，如下图所示：
image.png
看看随便进入一个android.support.design的BuildConfig，BuildConfig.DEBUG其实是为false的，其实我们希望BuildConfig.DEBUG为true，�但是事与愿违，而且这个错误还不容易发现。
image.png
为什么用AppConfig.IS_DEBUG就不会出现这样的问题呢，因为这是在我们自己的app下定义的，在那定义的？如下图所示，其实是在build.gradle中定义的，build.gradle可以定义很多类型的变量，可以很方便的达到我们需要的效果：
image.png
而在AppConfig我又封装了一层，避免了其他library中的build.gradle也定义了IS_DEBUG字段，所以只要AppConfig中的导包正确，就不会出现错误了，所以使用build.gradle中定义的字段时候，请务必再封装一层，代码如下图所示：
import com.zyp.BuildConfig;
public class AppConfig {
/**在build.gradle中配置的变量*/
