Android Studio - 第四十五期 Gradle manifestPlaceholders
最近在學習擼擼的代碼規範和寫法,有些心得,準備好好寫一寫~包括了多渠道打版(以前有寫過方法),工廠模式,mvp,以及最近剛封裝出來的多渠道多版本展示不同頁面的manifestPlaceholders的配置方法,大家應該也碰到過線上和線下環境的切換換地址,換私鑰的頭大問題,本篇就來解決這些問題。
先在androidmanifest文件配置一個節點,這裏以極光為例:
<meta-data android:name="JPUSH_APPKEY" android:value="${jush_appkey_value}" /> <meta-data android:name="SHOUCANG_CONFIG0" android:value="${SHOUCANG_CONFIG_VALUE0}" />
build.gradle:
buildTypes { release { //自定義buildconfig字段 buildConfigField("boolean", "APP_ENV", "true") //指定簽名為release signingConfig signingConfig.release //是否開啟混淆 minifyEnabled false proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘ //是否zip優化 zipAlignEnabled true //刪除一些無用資源 shrinkResources false // manifestPlaceholders = [ "jush_appkey_value": "release key" ] } debug { //自定義buildconfig字段 buildConfigField("boolean", "APP_ENV", "true") //指定簽名為release signingConfig signingConfig.release //是否開啟混淆 minifyEnabled false proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘ //是否zip優化 zipAlignEnabled true //刪除一些無用資源 shrinkResources false // manifestPlaceholders = [ "jush_appkey_value": "debug key" ] } }
在bulidtypes節點下有release節點和debug節點,正式簽名時就會走release節點的下編譯腳本,調試簽名時就會走debug節點。主要點就是manifestPlaceholders的用法,jpush_appkey對應的就是之前在androidmanifest文件配置的${jush_appkey_value}的這個值。
在程序入口出打上log,用來輸出key的值:
/** * 在程序入口出打上log,用來輸出key的值bufen */ private void jpush_key_manifest_xml_string() { String jpush_appkey; try { ApplicationInfo appInfo = getPackageManager() .getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA); jpush_appkey = appInfo.metaData.getString("JPUSH_APPKEY"); Log.e("jpush_appkey", "jpush_appkey=" + jpush_appkey); } catch (PackageManager.NameNotFoundException e) { e.printStackTrace(); } }
接下來給大家介紹多版本多頁面多apk的配置切換方法:舉個例子:如果你要一次性打七個版本,而且七個版本都是不同的頁面,但是頁面各個模塊大體一樣,只是順序和大小不同,你要怎麽做,別告訴我寫七個頁面分別打版哈~太low了~you know~這裏就利用多版本打版和manifestPlaceholders來實現需求。
首先是build.gradle:

flavor.manifestPlaceholders = [SHOUCANG_CONFIG_VALUE: ".shoucang.factorys.ShoucangFactory1", STATISTICS_VALUE: stValue] } else if (currentMode == demo2) { flavor.manifestPlaceholders = [SHOUCANG_CONFIG_VALUE: ".shoucang.factorys.ShoucangFactory2", STATISTICS_VALUE: stValue] } else if (currentMode == demo3) { flavor.manifestPlaceholders = [SHOUCANG_CONFIG_VALUE:

接著就是多版本的代碼判斷書寫:
@Override protected void onCreate(@Nullable Bundle savedInstanceState) { //TODO 多版本切換 寫此方法bufen which_version(); // ShoucangConfig0.config();//manifestPlaceholders的妙用 super.onCreate(savedInstanceState); } private void which_version() { if (ConstantNetUtil.VERSION_APK == NetConfig.version_name0) { ShoucangConfig.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name1) { ShoucangConfig1.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name2) { ShoucangConfig2.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name3) { ShoucangConfig3.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name4) { ShoucangConfig4.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name5) { ShoucangConfig5.config(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name6) { ShoucangConfig6.config(); } } //TODO 多版本模式bufen SparseArrayCompat<Class<? extends BaseFragment>> array = which_version_fragment_config();//demo private SparseArrayCompat<Class<? extends BaseFragment>> which_version_fragment_config() { if (ConstantNetUtil.VERSION_APK == NetConfig.version_name0) { return ShoucangConfig.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name1) { return ShoucangConfig1.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name2) { return ShoucangConfig2.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name3) { return ShoucangConfig3.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name4) { return ShoucangConfig4.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name5) { return ShoucangConfig5.getFragments(); } else if (ConstantNetUtil.VERSION_APK == NetConfig.version_name6) { return ShoucangConfig6.getFragments(); } return ShoucangConfig.getFragments(); }
這樣跑完apk你會發現會有神奇的事情發生,如下圖:(不同的apk版本出來的頁面也是不同的,但是只用了一份代碼。)
圖1:
圖2:
這樣做的好處在於,如果你的apk版本很多,需要給很多合作廠商提供定制化頁面,就可以用上了~
臥槽,今天噴了好多,希望大家回去自己細化一下,能幫到你~
