Change Android Eclipse settings to ignore error

Question

I reverse engineering an apk file and I edit some stuff in java files, and it gives me lot of errors BUT BEFORE THAT, I have already tested the original java files and resources from the apk that I reverse engineering without making any edit but it gives me the same errors which I had when I edit the java files and resources, is it possible to ignore all the errors in eclipse and export the apk to test or something to not have errors, here is an example for errors :

  public class DataHeper    
{    
  public SQLiteDatabase database = null;    
  public File databaseFile;    
  public String databaseName = "data.sqlite";

  Context mContext;    

  public DataHeper(Context paramContext)    
  {     
    this.mContext = paramContext;     
    this.databasePath = ("data/data/" + paramContext.getPackageName() +    "/data.sqlite");    
    this.databaseFile = new File(this.databasePath);    
    if (!this.databaseFile.exists());  
    try  
    {  
      deployDataBase(this.databaseName, this.databasePath);  
      return;  
    }  
    catch (IOException localIOException)  
    {  
      localIOException.printStackTrace();  
    }  
  }

    throws IOException

Here I have a error that told me:

Unreachable code
in:  new StringBuilder("UPDATE qod SET quote_id =   ").append(paramInt).append(",changed =   ").append(localDate.getTime()).append(",body =   \"\"").append(paramString).append("\"\" ;").toString(); 

and I have this error in lot of files
thanks in advance

Answer 1

Because you have return true in the line above, which makes it quit the while loop, that's why it is unreachable.

Then Java 7 doesn't work very well with android in.

Here is a thread about that to: stackoverflow.com/questions/9098684/

Get latest JDK and it should work fine!
