在TelephonyManager中增加了幾個api，編譯系統生成classes.jar後，app匯入引用TelephonyManager類時，ide提示TelephonyManager類沒有增加的那幾個api。檢視該TelephonyManager來源，發現是來自Android Studio配置的sdk。

執行下面兩步操作後，可指定ide首先引用我們修改的TelephonyManager類：

1、修改專案根目錄下的build.gradle

allprojects {
    repositories {
        jcenter()
    }
    +gradle.projectsEvaluated {
    +    tasks.withType(JavaCompile) {
    +        options.compilerArgs.add('-Xbootclasspath/p:app/libs/classes.jar')
    +    }
    +}
}
 

2、修改app目錄的build.gradle

+preBuild {
+    doLast {
+        def imlFile = file(project.name + ".iml")
+        println 'Change ' + project.name + '.iml order'
+        try {
+            def parsedXml = (new XmlParser()).parse(imlFile)
+            def jdkNode = parsedXml.component[1].orderEntry.find { it.'@type' == 'jdk' }
+            parsedXml.component[1].remove(jdkNode)
+            def sdkString = "Android API " + android.compileSdkVersion.substring("android-".length()) + " Platform"
+            new Node(parsedXml.component[1], 'orderEntry', ['type': 'jdk', 'jdkName': sdkString, 'jdkType': 'Android SDK'])
+            groovy.xml.XmlUtil.serialize(parsedXml, new FileOutputStream(imlFile))
+        } catch (FileNotFoundException e) {
+            // nop, iml not found
+        }
+    }
+}
