i have prefer / copy code from this and this
i copy this code its kinda old, there is already app-debug.apk (this use android.permission.SYSTEM_ALERT_WINDOW in the manifest) in the project download and i try its run normally but when i use the that code to my project its give me that error massage.
what else permission i must use?

This question has been solved by myself
UPDATE
make sure you have added permission in the manifest.
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
put this on onCreate or whatever you want to askPermission()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(this)) {
askPermission()
}
Method:
#TargetApi(23)
public void askPermission() {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, SYSTEM_ALERT_WINDOW_PERMISSION);
}

App crashes when Progress Dialog is open and user changes orientation [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
My application has a Progress Dialog for login process and when the orientation is changed while dialog box is open, app crashes.This all works fine, except when screen orientation changes while the dialog is up. At this point the app crashes. I am figuring out this issue from the last 3 nights but not able to get it, please help.

Add this configuration change in your Android manifest activity:
<activity
android:name="YourActivity"
android:configChanges="orientation|keyboardHidden|screenSize"/>

Why does this code seem not to find the MainActivity?

We are writing an android based Application that tracks several Mobilephone sensors now I tried compiling the code when suddenly this happend

Have you declared this MainActivity in AndroidManifest file?

Check AndroidManifest.xml
You should see your activity within the application tag like so:
<activity android:name="com.example.max.pswi.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

You need to initialize with values.
Double deslatituded, deslongituded, srclatituded, srclongituded;
You declare the doubles, but these are objects, not primitives. Therefore the default value is null. And the unboxing tries to get the primitive like
null.doubleValue()
Make them primitive or assign a default value like:
Double desLatituded = new Double(0);

I am not sure what is your error. But one of the scenario is
you declare class variables
private final LatLng end = new LatLng(deslatituded, deslongituded);
private final LatLng start = new LatLng(srclatituded, srclongituded);
Here deslatituded, deslongituded values must be null. Maybe this will the reason for the nullPoiner please check this.
You need to pass the values for this. Or just initialise the values like deslatituded=0 or something. This will save you from crash

Try this (and make sure your LatLng variables aren't final):
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps_activity_connect);
pref = getSharedPreferences("gps", Context.MODE_PRIVATE);
Bundle extras = getIntent().getExtras();
if (extras != null) {
deslatituded = extras.getDouble("deslatitude");
deslongituded = extras.getDouble("deslongitude");
srclatituded = extras.getDouble("srclatitude");
srclongituded = extras.getDouble("srclongitude");
// NEW CODE
end = new LatLng(deslatituded, deslongituded);
start = new LatLng(srclatituded, srclongituded);
// END NEW CODE
vechile = extras.getString("vechile");
if (!Utils.isConnected(getApplicationContext())) {
Toast.makeText(getApplicationContext(), "Internet not available. Cross check your internet connectivity and try again", Toast.LENGTH_LONG).show();
return;
}
if (!Utils.isGPSTurnOn(getApplicationContext())) {
showGPSDialog();
return;
}
}
}

Please check if your extras has the key "deslatitude"
like:
if(getIntent().hasCategory("deslatitude"))
{
deslatituded = extras.getDouble("deslatitude");
}
Log.e(TAG, "deslatitude: " + deslatituded );
And if your log prints the valuew then check it for all (deslat,deslong,srclat,srclong)

Are there any values in
extras.getDouble("deslatitude");
extras.getDouble("deslongitude");

Android App crashes on Lollipop

hi I am using google license checker on my app it works on API 19 and below but crashes on lollipop. I saw the code that has to be add to my license check code but I don't know where to put this code or what should I edit. here is my code
log:

Context mContext;
IBinder serviceBinder;
String deviceId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.splash);
mLicenseCheckerCallback = new MyLicenseCheckerCallback();
deviceId = Secure.getString(getContentResolver(), Secure.ANDROID_ID);
// Construct the LicenseChecker with a policy.
mChecker = new LicenseChecker(
this, (Policy) new ServerManagedPolicy(Splash.this, new AESObfuscator(SALT, getPackageName(), deviceId)),
BASE64_PUBLIC_KEY);
doCheck();
}
private class MyLicenseCheckerCallback implements LicenseCheckerCallback {
#Override
public void allow(int reason) {
// TODO Auto-generated method stub
if (isFinishing()) {
// Don't update UI if Activity is finishing.
return;
}
// Toast.makeText(Splash.this, "License Verified", Toast.LENGTH_SHORT).show();
Intent intent=new Intent(Splash.this,Home.class);
startActivity(intent);
finish();
// Should allow user access.
// so do nothing
}
#Override
public void dontAllow(int reason) {
// TODO Auto-generated method stub
if (isFinishing()) {
// Don't update UI if Activity is finishing.
return;
}
// Toast.makeText(Splash.this, "License Verification Failed", Toast.LENGTH_SHORT).show();
createDialog();
}
#Override
public void applicationError(int errorCode) {
// TODO Auto-generated method stub
}
}
#Override
protected void onDestroy() {
super.onDestroy();
mChecker.onDestroy();
}
private void doCheck() {
// mCheckLicenseButton.setEnabled(false);
setProgressBarIndeterminateVisibility(true);
/// mStatusText.setText(R.string.checking_license);
mChecker.checkAccess(mLicenseCheckerCallback);
}
public void createDialog(){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("PIRACY WARNING");
builder.setMessage("This application is not licensed. Please purchase it from Android Market. If you received this message in error, please contact Support.");
builder.setPositiveButton("Buy Now", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent marketIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(
"http://market.android.com/details?id=" + getPackageName()));
startActivity(marketIntent);
}
});
builder.setNegativeButton("Quit", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
and here is the other code which I got that this can solve my problem. but don't know where to put it.
Intent serviceIntent = new Intent(
new String(Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")));
serviceIntent.setPackage("com.android.vending");
boolean bindResult = mContext
.bindService(
serviceIntent,
this, // ServiceConnection.
Context.BIND_AUTO_CREATE);

Waiting for an official solution, the current solution consists in patching Google's LicenseChecker class
com.google.android.vending.licensing.LicenseChecker.checkAccess(LicenseChecker.java:150)
like this:
new String(
- Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U="))),
+ Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")))
+ .setPackage("com.android.vending"), // this fix the 'IllegalArgumentException: Service Intent must be explicit'
this, // ServiceConnection.
Adding package name with statement setPackage("com.android.vending") makes the Intent explicit, i.e., 'safe' (as requested by Android Lollipop )
Note:
Please pay attention as after modifying LicenseChecker class you must change the min sdk version from 3 to 4 (thanks russellhoff)
