Najaribu kutengeneza DeviceAdmin app kwa kutumia sample codes za android sdk. Nikiwa na launch hiyo application napata error activitynotfoundexception: unable to find activity class{com.example/com.example.DeviceAdminSample};

Manifest code

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

<!-- Device Admin Samples -->

<activity android:name="com.example.DeviceAdminSample$Controller"
android:label="@string/activity_sample_device_admin">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>


<receiver android:name="com.example.DeviceAdminSample"
android:label="@string/sample_device_admin"
android:description="@string/sample_device_admin_description"
androidermission="android.permission.BIND_DEVICE_ADMIN">
<meta-data android:name="android.app.device_admin"
android:resource="@xml/device_admin_sample" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>


//inner na outer java class

public class DeviceAdminSample extends DeviceAdminReceiver {

static SharedPreferences getSamplePreferences(Context context) {
return context.getSharedPreferences(DeviceAdminReceiver.class.getName(), 0);
}

static String PREF_PASSWORD_QUALITY = "password_quality";
static String PREF_PASSWORD_LENGTH = "password_length";
static String PREF_MAX_FAILED_PW = "max_failed_pw";

void showToast(Context context, CharSequence msg) {
Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
}

Override
public void onEnabled(Context context, Intent intent) {
showToast(context, "Sample Device Admin: enabled");
}

Override
public CharSequence onDisableRequested(Context context, Intent intent) {
return "This is an optional message to warn the user about disabling.";
}

Override
public void onDisabled(Context context, Intent intent) {
showToast(context, "Sample Device Admin: disabled");
}

Override
public void onPasswordChanged(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw changed");
}

Override
public void onPasswordFailed(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw failed");
}

Override
public void onPasswordSucceeded(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw succeeded");
}



public static class Controller extends Activity {
static final int RESULT_ENABLE = 1;

DevicePolicyManager mDPM;
ActivityManager mAM;
ComponentName mDeviceAdminSample;

Sifahamu tatizo liko sehemu gani.

Unatumie eclipse? Jaribu kuadd tena hiyo activity kwenye manifest ...... Nafikiri inashindwa kusoma hiyo activity.... Au jaribu hiyoclass iextend activity pia....

 

[Isaac Chikoma]

Natumia eclipse ,hiz code nimeziweka kama hao jamaa walivyoelekeza ila sielewi kwanini nikirun inashidwa kuona hiyo static class controller kwenye manifest, receiver haikubali kuextend kama activity,

 

[felijose]

Jaribu kifafanya controller iwe default laucher activity badala ya hiyo device adminsample....

 

[Isaac Chikoma]

Ok ngoja nijaribu

 

[Jaluo_Nyeupe]

Hapa mi napata kizunguzungu tu. Ila ngoja nifuatilie natamani kuwa hata na idea ya haya mavitu.

 

[felijose]

Kijana.. Jaribu... Ukiweka moyo utaweza tu.....

 

[ndupa]

hapa naona giza tu.....endeleeni ntakuaja tena...

 

[Isaac Chikoma]

Nimefanikisha mkuu! Thanks.

 

[figganigga]

Nimefanikisha mkuu! Thanks.

Umefanyaje?. miaa

 

[Isaac Chikoma]

Nilichofanya ni kutenganisha hizo nested classes inner na outer nimeweka kila moja kivyake, activity na receiver ziwe zinajitegemea.

Poa poa......
