I developed an android app ver 1.0 in which i stored the user data in shared preferences. Now I am developing ver 2.0 and I have the following questions about updating it
1. 导言 如何探测是否已安装了1.0版? 我指的是,它是一个纯粹的装置(直接的2.0安装),还是从1.0更新。
2. 结 论 如果被检测为1.0,我想将共享的优惠价值输入数据库。 在更新期间,共同的偏好是否超成文? 如何防止这种情况? 如果它们不成文,我就想写出一件把价值装上 load子的活动。
- What parameter should i set so that market gives notification that update is available. Should i set that in android manifest with same keystore?
请帮助我
感谢 你,
