简单整理一下packageManager的几个获取包信息的方法。下面的都是自己试验出来的
/** * 获取本机中所有在AndroidManefest.xml中定义过的Activity的所有信息，包括permission,theme,name等等 * 只要是在AndroidManefest.xml中的<Activity>标签中能填写的属性，这里就可以获取。由ActivityInfo的源码得知 * toString函数只是打印了一个activity的编号和他的名字。 * */ private void showActivityInfo() { for (PackageInfo pack : getPackageManager().getInstalledPackages( PackageManager.GET_ACTIVITIES)) { ActivityInfo[] activityInfos = pack.activities; // Log.d(TAG, "pack.packageName =qqqq= " + pack.packageName // + " pack.versionName =qqqq= " + pack.versionName // + " versionCode ==qqq= " + pack.versionCode); if (activityInfos != null) { for (ActivityInfo activityInfo : activityInfos) { Log.d(TAG, "activityInfos: " + activityInfo.toString() + " permission: " + activityInfo.permission); } } } } /** * 获取所有应用在AndroidManefest.xml中定义的Provider的信息，包括authority等。 与showActivity类似 */ private void showProviderInfo() { for (PackageInfo pack : getPackageManager().getInstalledPackages( PackageManager.GET_PROVIDERS)) { ProviderInfo[] providerInfos = pack.providers; // Log.d(TAG, "pack.packageName == " + pack.packageName // + " pack.versionName == " + pack.versionName // + " versionCode === " + pack.versionCode); if (providerInfos != null) { for (ProviderInfo providerInfo : providerInfos) { Log.d(TAG, "providerInfo: " + providerInfo.toString() + " authority: " + providerInfo.authority); } } } } /** * 获取手机中所有包，并打印出这些包都用到了哪些permission */ private void showPermission() { for (PackageInfo pack : getPackageManager().getInstalledPackages( PackageManager.GET_PERMISSIONS)) { if (pack.requestedPermissions != null) { Log.d(TAG, "*******************************************"); Log.d(TAG, "pack.packageName: " + pack.packageName); for (String per : pack.requestedPermissions) { Log.d(TAG, "permission ----- > " + per); } } } } 此乃原创，转载请注明出处。
