| ↳ | android.os.StrictMode.ThreadPolicy.Builder |
*** ** * ** ***
Creates[ThreadPolicy](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy)instances. Methods whose names start with`detect`specify what problems we should look for. Methods whose names start with`penalty`specify what we should do when we detect a problem.
You can call as many`detect`and`penalty`methods as you like. Currently order is insignificant: all penalties apply to all detected problems.
For example, detect everything and log anything that's found:
```
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.detectAll()
.penaltyLog()
.build();
StrictMode.setThreadPolicy(policy);
```

## Public constructors
### Builder
Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Builder ()
```
Creates a Builder that detects nothing and has no violations. (but note that[build()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder#build())will default to enabling[penaltyLog()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder#penaltyLog())if no other penalties are specified)
### Builder
Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### detectExplicitGc
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder detectExplicitGc ()
```
Detects calls to[Runtime.gc()](https://developer.android.com/reference/java/lang/Runtime#gc()).
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### detectNetwork

|
### detectResourceMismatches
Added in[API level 23](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder detectResourceMismatches ()
```
Enables detection of mismatches between defined resource types and getter calls.
This helps detect accidental type mismatches and potentially expensive type conversions when obtaining typed resources.
For example, a strict mode violation would be thrown when calling[TypedArray.getInt(int, int)](https://developer.android.com/reference/android/content/res/TypedArray#getInt(int,%20int))on an index that contains a String-type resource. If the string value can be parsed as an integer, this method call will return a value without crashing; however, the developer should format the resource as an integer to avoid unnecessary type conversion.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### detectUnbufferedIo
Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder detectUnbufferedIo ()
```
Detects unbuffered input/output operations.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### penaltyDeath
Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder penaltyDeath ()
```
Crashes the whole process on violation. This penalty runs at the end of all enabled penalties so you'll still get see logging or other violations before the process dies.
Unlike[penaltyDeathOnNetwork()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder#penaltyDeathOnNetwork()), this applies to disk reads, disk writes, and network usage if their corresponding detect flags are set.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### penaltyDeathOnNetwork
Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder penaltyDeathOnNetwork ()
```
Crashes the whole process on any network usage. Unlike[penaltyDeath()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder#penaltyDeath()), this penalty runs*before* anything else. You must still have called[detectNetwork()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder#detectNetwork())to enable this.
In the Honeycomb or later SDKs, this is on by default.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### penaltyDialog
Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder penaltyDialog ()
```
Shows an annoying dialog to the developer on detected violations, rate-limited to be only a little annoying.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
### penaltyDropBox
Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public StrictMode.ThreadPolicy.Builder penaltyDropBox ()
```
Enables detected violations log a stacktrace and timing data to the[DropBox](https://developer.android.com/reference/android/os/DropBoxManager)on policy violation. Intended mostly for platform integrators doing beta user field data collection.
| Returns ||
|-----------------------------------------------------------------------------------------------------------------------|------------------------------------|
| [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder) | This value cannot be`null`.
|
