读取文件转换成字节数组的代码

public byte[] getFile(String location){

FileConnection fc = null;

ByteArrayOutputStream bStrm = null;

InputStream is;

try{

fc = (FileConnection)Connector.open(location, Connector.READ);

//Check if it is more than 150kb, if so throw an exception

if((int)fc.fileSize() > 64000){

showInfo( "files too big " );

}

is = fc.openInputStream();

int ch;

bStrm = new ByteArrayOutputStream();

while ((ch = is.read()) != -1){

bStrm.write(ch);

}

return bStrm.toByteArray();

}catch(Exception e){
showInfo( "get files error " );
return null;
}finally{

if(fc != null){try{fc.close();}catch(Exception ee){}}

if(bStrm != null){try{bStrm.close();}catch(Exception ee){}}

}

}
