一、React-Native在6.0以下Android手機運作調試 預設$react-native run-android需要android6.0以上才能成功安裝應用 如何降低版本： 1、修改 項目根目錄\android\ build.gradle
dependencies { //classpath 'com.android.tools.build:gradle:2.2.3' classpath 'com.android.tools.build:gradle: 1.2.3'
// NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files }
再次執行$react-native run-android會提示修改 項目根目錄\android\ gradle\wrapper\gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists #distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip distributionUrl=https\://services.gradle.org/distributions/ gradle-2.2-all.zip 再次執行$react-native run-android會下載下傳 gradle-2.2-all.zip(下載下傳速度比較慢)，操作成功(我手機是android5.1)
