Android在开发中有时候要判断应用中是否有某项权限，或者想获取到某个应用的权限清单，可以使用以下方法
1) 判断应用是否具有某个权限
PackageManager pm = getPackageManager();
boolean permission = (PackageManager.PERMISSION_GRANTED ==
pm.checkPermission("android.permission.RECORD_AUDIO", "packageName"));
if (permission) {
showToast("有这个权限");
}else {
showToast("木有这个权限");
}
2)获取某个应用的权限清单
try {
PackageInfo pack = pm.getPackageInfo("packageName",PackageManager.GET_PERMISSIONS);</span>
String[] permissionStrings = pack.requestedPermissions;
showToast("权限清单--->" + permissionStrings.toString());
} catch (NameNotFoundException e) {
e.printStackTrace();
}
permissionStrings 是一个这样的字符串数组
[android.permission.INTERNET,
android.permission.READ_PHONE_STATE,
android.permission.READ_CONTACTS,
……
android.permission.READ_EXTERNAL_STORAGE,
android.permission.READ_CALL_LOG,
android.permission.WRITE_CALL_LOG]
