Question

我有这段代码。问题出在this.hash或this.getHash()。当我尝试将哈希值设置为方法checkHash()时，Log.d和Server（因为checkHash()向服务器发送值）说this.hash为"" }。为什么this.hash意外变空？

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(...) {
...
Connection conn = new Connection(getApplicationContext());
this.hash = this.getHash();
Log.d("OMG", this.getHash()); // returns correct HASH value
Log.d("OMG", this.hash); // returns correct hash value
String response = conn.checkHash(this.hash, device); // this method gets empty hash value

...
}

}

public String checkHash(String hash, String device) throws ServerException, NoInternetException {
    List<NameValuePair> query = new ArrayList<NameValuePair>();
    Log.d("INTERNAL", hash + " / " + device);
    query.add(new BasicNameValuePair("hash", hash));
    query.add(new BasicNameValuePair("key", this.KEY));
    query.add(new BasicNameValuePair("device", device));
    query.add(new BasicNameValuePair("method", "checkHash"));
    return this.post(query);
}

@覆盖 protected void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; 的setContentView（R.layout.activity_main）;

        try {
            // Checking hash
            String device = Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID);

            Connection conn = new Connection(getApplicationContext());
            this.hash = this.getHash();
            Log.d("LOVEISTRUE", this.hash);
            String response = conn.checkHash(this.hash, device);

            Log.d("HAVEALOOK", device + " / " + response);
            Log.d("HAVEALOOKRESPONSE", response);
            if (response.equals("ERR")) {
                Intent toProjects = new Intent(MainActivity.this, LoginActivity.class);
                this.startActivity(toProjects);
            }
            if (response.equals("OK")) {}
        } catch (Exceptions.ServerException e) {
            Intent toProjects = new Intent(MainActivity.this, LoginActivity.class);
            this.startActivity(toProjects);
        } catch (Exceptions.NoInternetException e) {
            Intent toProjects = new Intent(MainActivity.this, LoginActivity.class);
            this.startActivity(toProjects);
        }
