Android上程序閃退，讀取Manifest.xml配置檔案出錯

Android上程序閃退，都是在jni調用java代碼處異常

排查一：

前面以更換包名的版本編譯過，随便修改一下main.cpp然後重新編譯，問題沒解決

排查二：

還是懷疑包名的問題，修改jni中包名為錯誤包名，對比出錯内容，報錯内容不同。不過對定位沒有幫助

排查三：

關鍵地方列印日志資訊，

public static String getDeviceToken() {

Log.e("=======", "==================================kkkkkkkkkkkkkkkkk"); 

String xx = sCldComm.getDeviceInfo2(); 

Log.e("=======", "==========================" + xx); 

return xx; 

}

發現下面異常資訊

在java函數裡面出的問題，并不是jni調用間的問題，最終跟蹤getDeviceInfo2函數定位到問題處

ApplicationInfo appInfo;

appInfo = pm.getApplicationInfo(activity.getPackageName(), PackageManager.GET_META_DATA);

//String value = appInfo.metaData.getString(name);    

// Manifest.xml中配置會轉為Bundle結構，而該結構有類型差別。數字類型值預設轉為int

// 這裡使用getString導緻最終失敗

// 最新修改是先擷取Object對象，然後通過toString轉化

Object obj = appInfo.metaData.get(name); 

return obj.toString();
