嗨，大家即時進行自動更新後，在線教程，然後編輯代碼，以滿足我的需要..但我得到這個錯誤在我的logcat爲什麼我得到th java.lang.RuntimeException：無法啓動活動ComponentInfo
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.harrops.h20droidapp/com.example.harrops.h20droidapp.Homescreen}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.harrops.h20droidapp/com.example.harrops.h20droidapp.UpdateService}; have you declared this activity in your AndroidManifest.xml?
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2195)
可以有一個人請幫我
這是我的服務類
public class UpdateService extends Service {
public UpdateService() {
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
String url = "<MY Link for version>";
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
if (response != null) {
boolean resp = response.contains("<div class='post-body entry-content' id='post-body-6791062644900393367' itemprop='description articleBody'>\n" +
"1.1.8\n" +
"<div style='clear: both;'></div>");
if (!resp) {
//Dialog to show update
Intent intent1 = new Intent(UpdateService.this, UpdateDialog.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent1);
} else {
Toast.makeText(UpdateService.this, "No New Update Found..", Toast.LENGTH_LONG).show();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
queue.add(stringRequest);
return Service.START_NOT_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
}
那麼這是我的對話框類
public static Button btn;
public static String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Update";
public static File Dir = new File(path);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidAuthSession session = buildSession();
dropboxAPI = new DropboxAPI<AndroidAuthSession>(session);
Dir.mkdir();
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setIcon(R.mipmap.ic_launcher);
alertDialog.setTitle("update");
alertDialog.setMessage("New update Available...");
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "UPDATE", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
DownloadFromDropboxFromPath(path + "downloadFileFromDropbox", "Update/Myupdate.apk");
}
});
alertDialog.show();
}

private static final String APP_KEY = "********* **** ** **";
private static final String APP_SECRET = "XXX XX X X XX X";

}

runOnUiThread(new Runnable() {

Thread th = new Thread(new Runnable() {

if (file.exists()) file.delete();
try {
FileOutputStream outputStream = new FileOutputStream(file);
UpdateDialog.dropboxAPI.getFile(DropboxDownloadPathFrom, null, outputStream, null);
getMain().runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "File successfully downloaded.", Toast.LENGTH_SHORT).show();

});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == UploadFromFilemanager) {
final Uri currFileURI = intent.getData();
final String pathFrom = currFileURI.getPath();
Toast.makeText(getApplicationContext(), "Upload file ...", Toast.LENGTH_SHORT).show();
Thread th = new Thread(new Runnable() {

Toast.makeText(getApplicationContext(), "File successfully uploaded.", Toast.LENGTH_SHORT).show();
}
});
}
});
th.start();
}
if (requestCode == UploadFromSelectApp) {
Toast.makeText(getApplicationContext(), "Upload file ...", Toast.LENGTH_SHORT).show();
final Uri uri = intent.getData();
DropboxUploadPathFrom = getPath(getApplicationContext(), uri);
if (DropboxUploadPathFrom == null) {
DropboxUploadPathFrom = uri.getPath();
}
Thread th = new Thread(new Runnable() {
public void run() {
try {
final File file = new File(DropboxUploadPathFrom);
InputStream inputStream = getContentResolver().openInputStream(uri);
dropboxAPI.putFile("/db-test/" + DropboxUploadName + file.getName().substring(file.getName().lastIndexOf("."),
file.getName().length()), inputStream, file.length(), null, new ProgressListener() {
@Override
public long progressInterval() {
return 100;
}
@Override
public void onProgress(long arg0, long arg1) {
}
});
getMain().runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "File successfully uploaded.", Toast.LENGTH_SHORT).show();
}
});
} catch (Exception e) {

});
th.start();
}
super.onActivityResult(requestCode, resultCode, intent);
}
public String getPath(Context context, Uri contentUri) {
Cursor cursor = null;
try {
String[] proj = {MediaStore.Images.Media.DATA, MediaStore.Video.Media.DATA, MediaStore.Audio.Media.DATA};
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(column_index);
if (s != null) {
cursor.close();
return s;
}
} catch (Exception e) {
}
try {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(column_index);
if (s != null) {
cursor.close();
return s;
}
} catch (Exception e) {
}
try {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
String s = cursor.getString(column_index);
cursor.close();
return s;
} finally {
if (cursor != null) {
cursor.close();
}
}
}
public UpdateDialog getMain() {
return this;
}
} 然後最後我在我的主屏幕類中調用它。意圖
Intent intent = new Intent(Homescreen.this, UpdateService.class);
startActivity(intent);
謝謝@CommonWare –
