Question

All was working fine and dandy with Eclipse in Windows until I switched to Mac OS X Yosemite, using Android Studio V1.0. I imported the project as a Non-Android Studio project s

Answer 1

For Android Studio 2.2 you have To add compile option in gradle file of your project:

android { ... compileOptions { encoding "ISO-8859-1" sourceCompatibility JavaVersion.VERSION_1_7 targetCompatibility JavaVersion.VERSION_1_7 } }

Answer 2

Adding the following to build.gradle solves the problem :

android {
    ...
    compileOptions.encoding = 'ISO-8859-1'

Answer 3

I have encountered this problem, too. The reason for my problem is that I copy a file which is not encoded UTF-8 from Eclipse to Android Studio. A solution to this problem is that:

1. Make sure the default file encoding of your Android Studio is UTF-8: Settings --> File Encodings, set IDE Encoding, Project Encoding and Default encoding for properties files to UTF-8.
2. Copy your error file to a txt file and delete the error file.
3. Create a new file, its name is as the same as the deleted file.
4. Copy the content from the txt file to the new file.
