在配置自定义签名时出现了"Keystore was tampered with, or password was incorrect"错误！
参考文档发现：
If necessary, you can change the location/name of the debug keystore/key or supply a custom debug keystore/key to use. However, any custom debug keystore/key must use the same keystore/key names and passwords as the default debug key (as described above). (To do so in Eclipse/ADT, go to Windows > Preferences > Android > Build.)
因为配置的自定义的签名是为了发布时用的，密码也是自定义的公司名称，这样的话就跟默认的debug.keystore 密码android不同，从而导致报错！
那如此看来，自定义的debug签名就没有任何意义，至少我还没有发现。
自定义签名只需要在生成apk是由 Android Tools --> Export Signed Application Package
导出！
android 签名被篡改(Keystore was tampered with, or password was incorrect)
