private boolean installappforand235(string sourcefile, string filename, boolean issystemapp) {     boolean result = false;     try {         string destinationpath = ((issystemapp) ? path_system_app : path_user_app) + filename;         result = setexecpermision(destinationpath, true);         result = androidutils.runshellcommand(string.format("mv %s %s", sourcefile, destinationpath), false);         return result;     } catch (exception e) {         e.printstacktrace();     }      return result; }   private boolean installappforand442(string sourcefile, string filename, boolean issystemapp) {     boolean result = false;     try {         setexecpermision(sourcefile, true);         return androidutils.runshellcommand("pm install -r " + sourcefile, true);     } catch (exception e) {         e.printstacktrace();     }      return result; }  public static boolean runshellcommand(string command, boolean runassuperuser) {     boolean result = false;      try {         process process = null;         dataoutputstream dataoutputstream = null;          try {             if (runassuperuser) {                 process = runtime.getruntime().exec("su");                 dataoutputstream = new dataoutputstream(process.getoutputstream());                 dataoutputstream.writebytes(command + "\n");                 dataoutputstream.writebytes("exit\n");                 dataoutputstream.flush();             } else {                 process = runtime.getruntime().exec(command);             }              process.waitfor();              bufferedreader r = new bufferedreader(new inputstreamreader(process.geterrorstream()));             stringbuilder total = new stringbuilder();             string line;             while ((line = r.readline()) != null) {                 total.append(line).append('\n');             }                             log.d("run process error ", total.tostring());             log.d("run process exitvalue", string.valueof(process.exitvalue()));              if (process.exitvalue() == 0)                   result = true;             else                 result = false;          } catch (exception e) {             e.printstacktrace();         } {             try {                 if (dataoutputstream != null) {                     dataoutputstream.close();                 }                 process.destroy();             } catch (exception e) {             }         }     } catch (exception e) {         e.printstacktrace();     }      return result; } 

what have to?
