Android conversion to dalvik format failed with error 1 Solution

If an earlier version of ndroid (such as 1.5) is put into a later version (such as 2.2), the preceding error may occur. The solution is as follows:
1. If you do not modify the android sdk version, use the project clean command to act on a project.
(This processing method is only compatible with lower-version projects in the high version and is not truly upgraded)
2. To modify the android sdk version, follow these steps:
1) modify the SDK
Select the project, build path --> configure build path ---> library to delete the referenced low-version SDK,
Add External JARs, select SDK of later version, OK, and save
2) modify the classpath File
This file may contain this item: <classpathentry kind = "lib" path = "Your specified High Version address"
Change her to <classpathentry kind = "con" path = "com. android. ide. eclipse. adt. ANDROID_FRAMEWORK"/>
3) Modify AndroidManifest. xml
In the AndroidManifest. xml file, add the <uses-sdk android: minSdkVersion = "3"> </uses-sdk>
4) Modify default. properties (important)
Target = android-3 in the last line of the file (not used in the previous step), and save it as target = android-8.
Let's take a look at your project and the new android 2.2 project structure.
