android 簽名被篡改(Keystore was tampered with, or password was incorrect)

在配置自定義簽名時出現了"Keystore was tampered with, or password was incorrect"錯誤！ 

參考文檔發現： 

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.) 

因為配置的自定義的簽名是為了發布時用的，密碼也是自定義的公司名稱，這樣的話就跟默認的debug.keystore 密碼android不同，從而導致報錯！ 

那如此看來，自定義的debug簽名就沒有任何意義，至少我還沒有發現。 

自定義簽名只需要在生成apk是由 Android Tools --> Export Signed Application Package 
導出！
