    <p>i have a problem with RSA encryption and decryption. I'm developing in android and would like to outsource the RSA encryption and decryption. My source code worked well before i tried to outsource it.</p> <p>I created a private key and public key and saved it as private.key and public.key. The error is a ClassNotFoundException caused by this method:</p> <pre><code>public Key getPrivateKey(){ try { InputStream fis = activity.getResources().openRawResource(R.raw.private); ObjectInputStream ois = new ObjectInputStream(fis); Key RSAprivateKey = (Key)ois.readObject(); return RSAprivateKey; } catch (FileNotFoundException e) { Log.e("FileNotFound","FileNotFound"); e.printStackTrace(); } catch (IOException e) { Log.e("IOEXception","IOEXception"); e.printStackTrace(); } catch (ClassNotFoundException e) { Log.e("ClassNotFound","ClassNotFound"); Log.e("Errro", "Error: "+ e.getMessage()); Log.e("error", e.toString()); e.printStackTrace(); } return null; } </code></pre> <p>I looked at the logcat and got this error message:</p> <pre><code>E/ClassNotFound(1205): ClassNotFound 03-19 13:54:52.176: E/Errro(1205): Error: com.android.org.bouncycastle.jce.provider.JCERSAPrivateCrtKey 03-19 13:54:52.176: E/error(1205): java.lang.ClassNotFoundException: com.android.org.bouncycastle.jce.provider.JCERSAPrivateCrtKey </code></pre> <p>I hope you understand my problem, because English is not my native language.</p> <p>Edit: I found out that the problem is not caused by outsourcing the code. So i guess the topic can be marked as solved.</p>

    1. COFYI - your logging is very weird. You probably just want one `catch (Exception e)` statement containing `Log.e(TAG, "Error loading key", e);`, where `TAG` is a static string defined elsewhere, e.g. `private static final String TAG = MyActivity.class.getName();`.

    3. COThere is no such thing as "marking it as solved". You can however delete the question if it won't be if help to anyone else.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
