我反向设计一个apk文件，我在java文件中编辑了一些东西，它给了我很多错误但是之前，我已经测试了原始的java文件和来自apk的资源，我进行了逆向工程而没有进行任何编辑但它给了我与编辑java文件和资源时相同的错误，是否可以忽略eclipse中的所有错误并导出apk进行测试或者没有错误的东西， 这是一个错误的例子：
public class DataHeper
{
public SQLiteDatabase database = null;
public File databaseFile;
public String databaseName = "data.sqlite";
public String databasePath = "";
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());

{
deployDataBase(this.databaseName, this.databasePath);
return;

我有一个错误告诉我：
Unreachable code
in: new StringBuilder("UPDATE qod SET quote_id = ").append(paramInt).append(",changed = ").append(localDate.getTime()).append(",body = \"\"").append(paramString).append("\"\" ;").toString();
我在很多文件中都有这个错误 提前谢谢
答案 0 :(得分：1)
因为你在上面的行中返回true，这使得它退出while循环，这就是它无法访问的原因。
然后Java 7与android in./ / p>的效果不佳
以下是关于此的主题： stackoverflow.com/questions/9098684 /
获取最新的JDK，它应该可以正常工作！
