Android - 使用 apktool 将项目构建到 APK 文件时出错

Question

I have an APK file named: MyApp.apk. First I decode it using apktool:

apktool d MyApp.apk

It generates project folder: MyApp. Then I import it to Eclipse to edit it.
I create a new class as an Activity inside the MyApp project.
After finishing, I export the project to an APK file using apktool again:

apk b MyApp

It generates an APK file which I name Final_MyApp.apk. After, I sign it.
When I install Final_MyApp.apk using:

adb install Final_MyApp.apk

My application does not run. How can I fix it?

Answer 1

adb install only installs your application on the device.
To start your application, you have to call the activity manager (am)

adb shell am start -n com.package.name/com.package.name.ActivityName

Answer 2

I think you cannot include your new activity into your android manifest file. That's why your APK does not run.

Also store your apk in C or D folder and try like this

adb install C:\Final_MyApp.apk

Answer 3

When APK applications are built by apktool, there can be problems if the project folders or files do not use an 8 character file extension. There is no need for any version markers at all in either folders or filenames to get this error message.

Do you know how many bytes your app's "META-INF/" information should take? Each entry has 4 bytes! So what does that mean? It means that one kilobyte of folder/file data will only take up two kilobytes on disk, but yet claim four megabytes when an application is built - wayyy too much space to use! Remember the APK meant for distribution needs to be lean and trim to save SDK device storage

or, An APK refers to an Android application package, and while there's no "apktool" we're aware of, the question likely refers to the apktool website. There are a number of errors that can generate such a message, but the one it sounds like you'll want is called W2OTA error. This is related to how APK files need three pieces of code (in addition to assets) in order for them to be converted properly. The three pieces of codes are: Dalvik Executable (.dex), compiled version of Android Resources (.apk), and Application Description file (.apk). You can follow tutorials on how edit these files and install them onto your phone using Simple Recovery Tool v1
