speed up the power consumption. These development concepts directly affect the user's final experience, so let's talk about how to optimize the development of the user experience orientation in Android.

permissions based on digital certificates. Applications can share overviews or data with other programs to those that have the same digital credentials as themselves. Assuming that the protectionlevel of a permission (permission) is signature, this permission can only be granted to programs that have the same digital certificate as the package in which the permission resides. when signing, you need to consider the validity period of the digital certi

The example in this article describes how the Android implementation will apply crash information to developers and restart applications. Share to everyone for your reference, specific as follows: In the development process, although tested, but after the release, in the vast number of users in a variety of operating environment and operation, may occur some unexpected errors cause the program crashes. Collecting these error messages and feeding them
