The APK that is installed on the Android phone requires a signature, and this article describes how to create your own signature and export apk from Eclipse.
Method/Step
1. Select an Android project in Eclipse and click Export in the right mouse button menu:
2, choose "Android"->; " Export Android Application ", click" Next ":
3, because we have selected the project before, so directly click "Next",
4, since we have not keystore, so select "Create new KeyStore", and then specify the KeyStore path and password (assuming 123456). Finally click "Next".
5, enter the alias name (a keystore can have multiple alias) and the alias corresponding to the password (assuming 123123), specify the validity of the alias (here 100, for 100 years). The text boxes below the interface to enter the information to represent their identity, you must enter at least one, here I entered my own name pinyin. Finally click "Next".
6, enter the name of the apk you want to import, and then click Finish. So we get a signed apk.
