以下是我的代码我是电子邮件
Below is my code in which I am sending the email

snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_SYNCED);
Intent broadcastSyc = new Intent();
broadcastSyc.setAction(Common.GetSyncImageAction());
broadcastSyc.putExtra("STATUS", true);
mContext.sendBroadcast(broadcastSyc);
sendImage(mContext);
BackgroundMail.newBuilder(mContext)
.withUsername("gmail id")
.withPassword("pass")
.withMailto("gmail id")
.withType(BackgroundMail.TYPE_PLAIN)

.withBody("Meter #" + msn + " is "+ com+ " and "+ status)
.send();
}
如何解决此问题？任何帮助都将受到高度赞赏
How can i resolve this issue? Any help would be highly appreciated
注意：电子邮件是在提交表单时发送的，保存后我没有使用任何对话框。
Note: The email is sent when the form is submitted and after saving I am not using any dialog.

以下是 BackgroudMailer 类函数
public class SendEmailTask extends AsyncTask<String, Void, Boolean> {
private ProgressDialog progressDialog;
public SendEmailTask() { //error onPostExecute(BackgroundMail.java:265)
}
protected void onPreExecute() {
super.onPreExecute();
if(BackgroundMail.this.processVisibility) {
this.progressDialog = new ProgressDialog(BackgroundMail.this.mContext);
this.progressDialog.setMessage(BackgroundMail.this.sendingMessage);
this.progressDialog.setCancelable(false);
this.progressDialog.show();
}
}
protected Boolean doInBackground(String... arg0) {
try {
GmailSender sender = new GmailSender(BackgroundMail.this.username, BackgroundMail.this.password);
if(!BackgroundMail.this.attachments.isEmpty()) {
for(int i = 0; i < BackgroundMail.this.attachments.size(); ++i) {
if(!((String)BackgroundMail.this.attachments.get(i)).isEmpty()) {
sender.addAttachment((String)BackgroundMail.this.attachments.get(i));
}
}
}
sender.sendMail(BackgroundMail.this.subject, BackgroundMail.this.body, BackgroundMail.this.username, BackgroundMail.this.mailto, BackgroundMail.this.type);
} catch (Exception var4) {
var4.printStackTrace();
return Boolean.valueOf(false);
}
return Boolean.valueOf(true);
}
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
if(BackgroundMail.this.processVisibility) {
this.progressDialog.dismiss(); // error onPostExecute(BackgroundMail.java:302)
if(result.booleanValue()) {
if(!TextUtils.isEmpty(BackgroundMail.this.sendingMessageSuccess)) {
Toast.makeText(BackgroundMail.this.mContext, BackgroundMail.this.sendingMessageSuccess, 0).show();
}
if(BackgroundMail.this.onSuccessCallback != null) {
BackgroundMail.this.onSuccessCallback.onSuccess();
}
} else {
if(!TextUtils.isEmpty(BackgroundMail.this.sendingMessageError)) {
Toast.makeText(BackgroundMail.this.mContext, BackgroundMail.this.sendingMessageError, 0).show();
}
if(BackgroundMail.this.onFailCallback != null) {
BackgroundMail.this.onFailCallback.onFail();
}
}
}
}
}
问题是我无法编辑它，因为文件被锁定。
The problem is I cannot edit it as the file is locked.
推荐答案
在onPostExecute中你解雇对话框没有检查它是否实际显示：
in onPostExecute you dismiss the dialog without checking if it is actually shown:
this.progressDialog.dismiss();
为此添加一个isShowing检查（以及以防万一的空检查）
add a check of isShowing for that (and a null-check just in case..)
if (progressDialog != null && progressDialog.isShowing()) {
progressDialog.dismiss();
}
此外，我看到您对上下文使用静态引用。那可以导致内存泄漏，但这只是一个侧面说明。
Also I see that you use static references to contexts. That can lead to memory leaks, but that is just a side note.
